You can put this solution on YOUR website! Sam and harry started running at the same time from the opposite ends of the diameter of a circular track .
Both of them were running in the clock wise direction.
Sam took 12 minutes to run around the track once while Harry took 15 minutes to do the same .
How long did Sam take to run past Harry for the first time?
:
ONe way to do this just assign a distance around the track, 600 meters
then
600/12 = 50 m/min is Sam's speed
and
600/15 = 40 m/min is Harry's speed
:
When they start they are 300 meters apart (opposite sides of the round track)
Their relative speed 50 - 40 = 10 m/min
then
t =
t = 30 minutes for Sam to catch Harry
