Not sure how to find the distance

Question

A cyclist traveled at a rate of 24mi/hr to visit a nearby town. The cyclist averaged 18mi/hr on the return trip. If the round trip took 4.9 hours what is the distance to the nearby town?

Answer 1

Let the distance be d miles

Time taken to go = d/24

Time taken on the return trip =d/18

 Total time for round trip = d/24 +d/18 = 4.9

Solve the equation . you get d = 50.4 miles.
