Say a fisherman's boat burns five gallons per hour, if he fishes for eight hours does that mean he burns 40g?

The boat will only burn gas if the engine is running. He would only burn 10 gallons, because the boat was only running for 2 hours. So the fuel efficiency of his boat is 5 gal/hour, but the average amount of fuel used on his voyage was one and a quarter gallons per hour.

I think you can exclude the drifting. The question sounds like its meant to throw you off because if he used his engine while drifting too then yes he would burn through all his gas.

If it takes two hours to get to the spot then thats 10 gallons.

Anchor. Drift around for six hours.

Then go back which would take another 10 gallons.

So total the fisherman would have used 20 gallons on his trip and have 20 gallons left.

Plus any fisherman knows that when you leave your engine running while anchored it scares all the fish away!

If this is a homework question... Indeed, your "fisherman" burned 20 gallons of gas ie: 2 hours out to his favorite fishing hole - 2 hours back in to shore = total of 4 hours @ 5 gallons an hour = 20 gallons. If he is drift fishing, the engine is off, and he is not burning gas.

If however... your "husband's pay" was short by $150.00 or so... and he claims he went fishing for 8 hours and burned it all up in gas... well... that sounds a little fishy to me also. lol

Have a great Day!

As described, he would burn less than 40 gallons . Even if he left the engines idling in neutral after reaching his fishing spot and anchoring, due to the motor(s) not working as hard. Now if he drifts for six hours, he might use up 4o gallons total returning home depending on the distance drifted!

What the hell is with all the unfamiliar names? Me being a diehard, hard-to-the-core, through-'n-through bass fisherman that's been fishing his entire life that takes his bass fishing very seriously, I can easily spend 8, 10, 12, even 16 hours or more fishing because that's how much I love it. Every angler though, whether a man or a woman, has their own reasons for fishing for so many hours. At the lake I fish, it only takes that one specially placed cast to hook THE bass of a lifetime.

when the motor isn't running it doesn't use fuel. usually a fisherman uses the motor to get to his spot and then uses the trolling motor which is electric to cruise around the area.

GPH & MPH is what he is talking about> Crusing speed 5 GPH> Not fishing>

It means he only uses 10g.
