If someone could help me do this question I could really appreciate it. I'm not trying to get people to do my homework for me but I missed the class for this calculation and now I can't figure it out - I've done the rest of the assignment but don't know how to do this one last one.

Here's the question:

According to Hubble's law, with H0=70km/s/Mpc, how long will it take for the distance from the Milky Way Galaxy to the Virgo Cluster to double?

The answer is to be in seconds

also, when should I take a pregnancy test? I don't want to wait to see if I miss my period because that wouldn't be for a couple weeks.

I met this guy on the weekend. I met him through a mutual friend. We were drinking together and stuff in a group before going out to the bar and I just thought he was really sweet.. he wasn't really hot or anything but something about him kinda drew me in. We got to the bar, played pool, I lost all my other friends because it was so busy so I ended up just hanging out with him all night. We danced, made out, talked, he bought me food, and actually had a really good night. He smoothly got his number into my phone when he asked me about something I'd done before and he wanted me to tell him how to do it sometime. While we were talking about it, he once again smoothly got me to put my number into his phone this time. When I accidentally only put my name and not my number (I was a little tipsy, but nothing extreme!) he made sure he got my actual number. We ended up going back to his place, cuddling on the couch and talking more. We fooled around a little but didn't have sex. I had to leave because I was supposed to be staying at a friend's house. He kissed me bye and that was that. The next day our mutual friend asked him about it and what not, he wouldn't say much, told her she would have to ask me. I've since then added him on facebook (yesterday, two days after our night out) and he has yet to accept my friend request, or text me. It's been three days since everything, and I kinda half expected him to have texted me today. Is it okay to text him first? Should I wait now since I've made a move by adding him on facebook? I don't want to seem desperate or something, but I actually thought he was really sweet, a nice change from the guys I'm used to. It just gets so confusing when guys actually make an effort to get your number but then never text you. Any suggestions? Thanks!!!

going out for new years eve and my friends and I all decided to dress up. I'm going for a black, gold, and nude/ beige colour scheme but want to add a small bit of colour to make it a bit different (colour for some accessories, nails, etc.) any suggestions of what would look good??

There's this guy I've been really good friends with for about five years now. Friends, that's it. But then I noticed when I came home from university this summer he was friendlier than normal.. and I didn't really mind. He's been acting really flirty, he'd hug me every time he saw me, etc. Then one party he asked me to stay over but I had to go home, and since then we've been texting and such. He's super flirty over texts, and started saying stuff like "we should hang out" or when I'd say I was having a nap after work he'd say something like "I wish I was there too" So I was getting a little nervous just because it was a big change from our previous relationship. But we went camping this previous weekend with a bunch of people and we pretty much knew something was going to happen. Except it didn't. Miscommunications and stuff and we ended up spending each night separate. He seemed really weird around me too, barely talking, talking to my girlfriends more than me. I didn't really know how to take it. So I texted him yesterday and it totally wasn't like our usual conversations. Instead of me being the slightly timid one now it's him. He seemed so serious, not taking any jokes. Then randomly it'd seem like he was night, but then he'd go cold again. Now when I said we should hang out he's like "yaaa maybeee! but i work a lot and am usually pretty tired" Why is he doing this? I feel like it's completely flipped and I don't know what to do! Someone please help! Explain to me why he's acting so different, and is there anything I can do?!

So there was this big camping thing and i ended up making out with this guy on friday night. it was pretty intense and went on for a while but i didn't let it go any further. the saturday nothing really happened but he was clearly still interested in me, glancing over casually at me whenever he saw me with other people. then sunday night we ended up hooking up again but this time i gave him head. we didn't exchange numbers but he's a friend of my older sister's (he's two years older than me). i'll probably see him around really soon and don't really know what to do. i'm a virgin and know that if we were to hang out again he would probably want sex but i don't think i'm ready for that. should i hang out with him if he asks? any tips at all on what to do with this situation?
