Concept explainers
A bicyclist rides 24 mi against a wind and returns 24 mi with the same wind. His average speed for the return trip traveling with the wind is 8 mph faster than his speed going out against the wind. If x represents the bicyclist’s speed going out against the wind, then the total time, t, required for the round trip is given by
a. Find the time required for the round trip if the cyclist rides 12 mph against the wind.
b. Find the time required for the round trip if the cyclist rides 24 mph against the wind.
