I did it the longer way..

Distance = Speed x Time

As both are covering the same distance

Speed (H) x Time (H) = Speed (C) x Time (C)
=> (4 miles/60 mins) x Time (H) = (20 miles/60 mins) x 5 mins
=> Time (H) = 25 mins

The wait time for the cyclist will be 25 mins - 5 mins = 20 mins

This is my approach too.
