A family is driving 600 miles. Assuming they stop to get gas 3 times and eat 2 times, how many hours will it take them to reach their destination? How would you estimate the time?

Lol very badly. I have been stuck on the damn thing for like a half hour. Thats all the thing says. It dont give me how fast they are going or anything.

You cannot make an estimation of the time it takes for the trip without an estimate of the speed they are traveling. Find the average speed when they are driving, divide the distance of the trip by this average speed, then add the time for the stops. That is your estimate of the trips total time.

I'd first have to know how fast they're driving, how long it would take to get gas, and how long it would take to eat. Estimating a driving speed of 65 MPH, 5 minutes to get gas, and 45 minutes to eat, you have 45+45+5+5+5 = 105 minutes of non- driving time and 600*60/65 = 600*12/13 = about 554 minutes of driving time. The total would then be 659 minutes of time, which since we're estimating could be rounded up to 11 hours. Obviously changing some of the factors would change the time.

are you serious? A family of four would take at least 15 hours ill tell you why
say they go at 60 mph thats 10 hours there
stopping for gas is like 1 hour total
eat 2 times is like 2 hours (finding a place and getting something everyone likes)
thats 13 hours, and then they don't actually go at 60mph the whole way so add another 2 hours and there you go
15 hours

Too much unknowns here to give any resemblance of a credible answer. What sort of roads are being traveled? How long are the meals going to take? But for arguments sake let's say the average speed is 60mph. That's 10 hrs. Half hour per meal. Makes it 11 hours. And 5 minutes per gas stop. So that'd be about 11hours and 15 minutes. If I had to guess.

Taking the formulae D = S x T into consideration...
Speed, as well as the time taken to rest is required to solve this problem. How long did they stop to eat and get gas? Are they travelling at constant speed?
Try to add details to your question, and maybe I could figure that out.

there are some unknown variables here.
To solve this problem, we need the following information
1) Average speed (hourly) of the vehicle (say X miles/hr)
2) Duration of each of the stop (3 times for gas and two times to eat) (say G1, G2, G3 hours each for gas and E1, E2 hours each for eating).
Then, total time of travel = Driving time + Stopping time
==> (600/X) hrs + G1+G2+G3+E1+E2 hours

You would need to know three things: how fast they drive; how much time it takes to get gas; how long it takes to eat. Then you could solve the problem.

Estimate their average driving speed, the time they will spend eating, and the time they will spend getting gas.
Then sum the time they are stopped, and the distance divided by the average speed.

Depends how fast they're driving...
And how badly you want to get your homework right.

okay first off you dont' have there MPH so you can't figure out the time...
