Question

A car traveling 60 mph on the highway gets 28 miles per gallon. Write a function that represent the distance d (t) in miles that the car travels in t hours.

Answer 1

d(t)=60t

 

read 60mph as 60 miles/hour

 

that means this car will go 60 miles in 1 hour, 120 miles in 2 hours and 180 miles in 3 hours

 

so if you travel for 4 hours, plug in 4 for t and find d(t).

 

d(4)=60(4)

d(4)=240
