You can put this solution on YOUR website! Ms. Walker drives to work at a speed of 60 miles per hour. On her trip home from work, she travels along the same route at a speed of 40 miles per hour. If her round trip takes 1 hour to complete, how many miles does Ms. Walker drive each way?
-------
To-work DATA:
rate = 60 mph ; distance = x mi ; time = x/60 hrs
-----
From-work DATA:
rate = 40 mph ; distance = x mi ; time = x/40 hrs.
------
Equation:
time + time = 1 hr
x/60 + x/40 = 1 hr
2x + 3x = 120
5x = 120
x = 24 miles
