***
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)
..
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
