A and B participate in a 5000 m bicycle race which is being run on a circular track of 500 m. If the speed of A and B are 20 m/s and 10 m/s respectively, what is the distance covered by A when he passes B for
the seventh time ?  Pick:
A) 2500
B) 2800
C) 4000 m
D) Situation is not possible
E) None of these
Track length = 500 m   Speed of A and B are 20m/s and 10 m/s respectively   Time taken by them to meet = length/ relative speed = 500/(20-10) 50 sec.   Time taken to meet for the 7th time = 7 *50=

<output>350</output>
350 sec ……..(1)   Total duration of race= total legth of race/ speed   = 500/20 = 250 sec ……..(2)   From (1) and (2) we can find out that 7th time meeting is not possible.   Answer: Situation is not possible
