There is 500km between Oslo and Bergen. A regular train starts from Oslo at. 08:00 and drive towards Bergen at a steady speed of 80 km/h.?

as a reference :Oslo = 0

Train A:

Since t = t

A = 80t +0

Train B

at 8:00 , t = 0

10:00 , train start travel 2 hours later

but it is 500 miles away from Oslo to start with.

B= 500 + -100(t-2)= -100t +200 +500

B = -100t + 700

when does A = B

80t= -100t + 700

180t = 700

t= 700/180 = 70/18 = 35/9 = 3 8/9 hours

3 8/9 hours = 3 + 8/9 hours = 3 hours +8/9*60 minutes

480/9 = minutes = 53.33333 = 53 minutes and 20 seconds

8:00 + 3 Hours + 53 minutes + 20 seconds

Time = 11:53:20

distance from Oslo

dist= 80t= 80*3 8/9 = 311 1/9 Miles
