Answer
given,
speed of the fastest runner = 6.2 m/s
speed of the slower runner = 5.5 m/s
Assume, we need to calculate time when both the runner meet for the first time.
distance cover by the fast runner = distance cover by the slow runner
6.2 t = 5.5 t + 200
0.7 t = 200
t = 285.71 s
time after which both the runner meet.
Distance they covered after starting
D = s x t
D = 6.2 x 285.71
D = 1771.43 m.
now, calculating the second time both will meet.
they will take double time to meet again
t' = 2 x 285.71
t '= 571.42 s
