# find a linear function given an odometer reading, time, and the fuel tank reading.

when David Arnold started out on his trip his odometer read 45973 and his fuel gauge read 7/8 full. Exactly 1hr and 48 min later his the odometer read 46081 and the fuel gauge read 1/2 full. Find an equation for the linear function of the fuel gauge reading

Assume that this would be linear. I am having trouble figuring out what is needed of me and how to do what I need to do. I appreciate any help you can offer. -Adi

Do you want a function relating mileage and fuel or mileage and time or miles per tank?

from what I understand, I need to relate miles and fuel. the problem says "under what conditions does it seem reasonable that the odometer readings would be a linear function of the fuel gauge reading"
