You can put this solution on YOUR website! Two cyclists ride along a circular path whose circumference is 10 km.
The two cyclists start at the same time, from diametrically opposite positions.
The first cyclist goes at a constant speed of 30 km/h in the clockwise direction, while the second goes at a constant speed of 20 km/h in the counterclockwise direction.
They both cycle for 1 hour. How many times do they meet?
:
Find how long it will take them to meet the 1st time (t)
30t + 20t = 10
50t = 10
t =
t = .2 hrs to meet the 1st time
then = 5 times they will meet in 1 hr
