Question

A car traveled 36 miles in 45 minutes. The car traveled at a constant speed. If the car continues to travels at this rate which equation can be used to determine y the total number of miles the car will travel in x hours?

Answer 1

45 minutes is 3/4 of an hour.

Divide 36 miles by 3/4 to find the number of miles traveled in one hour:

36 / 0.75 = 48 miles per hour.

Now you can multiply number of hours (x) by 48 to find total miles:

y = 48x
