5. When David started out on his trip, his odometer read 45973 & his fuel gauge read 7/8 full. Exactly 1h
48min later, the odometer read 46081 & the fuel gauge read 1/2 full.
a) Under what conditions does it seems reasonable that the odometer reading would be a linear function of
the fuel gauge reading?
b) Find an equation for the linear function.
