Segways
Thanks Transportation

Three segways are travelling along a road going in the same direction. Ashton is a certain distance behind Beonce Charlize is twice that distance in front of Beonce. Each segway travels at its own uniform rate of speed. As a result, Ashton passes Beonce in seven minutes, and passes Charlize five minutes later. Question:  In how many minutes after Ashton would Beonce pass Charlize? See answer
