Q) Three Sprinters A,B&C had to sprint from points  P & Q and  back again (starting in that order). The time interval between the three sprinters A,B,C was 5 secs each (i.e A(T)>B(T)>C(T) ). The Sprinters passed a certain point R,which is somewhere between P & Q, simultaneously (none of them having reached Q yet). Having reached Q and reversed  the direction , the third sprinter met the second one 9m short of Q and met the  first sprinter 15m short of Q. Find the speed of the first sprinter if the distance between PQ is equal to 55m.

a) 4 m/s b) 3 m/s c) 2 m/s d) 1 m/s

P.S : Answer with solution please....any simple ways to calculate the same are welcome! 😃
