Question 863520
Two cyclists travel in opposite directions around a 5.6-mile circular trail. They start at the same time. The first cyclist completes the trail in 22 minutes and the second in 28 minutes. At what time do they pass each other?
***
let x=time they pass each other(travel time)
speed of first cyclist=5.6/22(miles/min)
speed of second cyclist=5.6/28(miles/min)
distance=speed*travel time (travel time same for both runners)

{{{5.6x/22+5.6x/28=5.6}}}
LCD:22*28
156.8x+123.2x=3449.6
280x=3449.6
x=12.32
time they pass each other=12.32 min after starting
