A truck can travel 240 miles in the same time that it takes a car to travel 330 miles. If the​ truck's rate is 15 miles per hour slower than the​ car's, find the average rate for each.

Answer 1

r represents car's rate

r - 15 represents truck's rate

330 / r represents car's time

240 / (r - 15) represents truck's time

330 / r = 240 ./ (r - 15)

Can you solve for r and answer?
