A student walks from home to school and returns riding on a bus along the same route. The entire trip takes 40 minutes. If the bus travels 7 times as fast as the student can walk, how long would it take the student to walk in both directions?
--------
Walking 1/7 as fast as riding --> 7 times as many minutes walking
t = time riding
7t = time walking
t + 7t = 40 min
t = 5 min
----------------
Walking both ways --> 7t + 7t
= 70 minutes
