A cyclist traveled at a rate of 32 MPH to visit a nearby tow

A cyclist traveled at a rate of 32 MPH to visit a nearby town. The cyclist averaged 10 MPH on the return trip. If the round trip took 6.3 hours, find the distance to the nearby town.

Solution

To-town DATA:
rate = 32 mph ; distance = x miles ; time = d/r = x/32 hrs
---------------------
From-town DATA:
rate = 22 mph ; distance = x miles ; time = d/r = x/22 hrs
---------------------
Equation:
time + time = 6.3 hrs
x/32 + x/22 = 6.3 hrs
---
Multiply thru by 32*22 to get:
22x + 32x = 22*32*6.3
54x = 4435.2
x = 82.13.. miles (distance to the town)
