Question

The distance traveled at a constant speed is directly proportional to

the time spent traveling. If Lynnell traveled 70 miles in 3.5 hours, how
many miles will Lynnell travel in 4 hours at the same constant speed?

Answer 1

80 mi.

Explanation:

There are a couple ways to solve this problem. I will show you one. First, let's find the rate of travel.

D = RT

70 = 3.5R

R = 70/3.5 = 20

Using that speed, we now get

D = 20(4) = 80 mi.
