Two runners starts simultaneously from the same point one a circular 200 m track in the same direction. Their speeds are 6.2 ms-1 and 5.5 ms-1. How far from the starting point the faster will overcome the slower?
A
150 m away from the starting point
B
170 m away from the starting point
C
120 m away from the starting point
D
None of these
Answer
170 m away from the starting point
Explanation
Solution
200 = (6.2 – 5.5)t or t = 285.714 s
s = (6.2 × 285.714) = 1770m (faster), 1770 – 8 × 200 = 170
Thus 170 m away from the starting point along the track in the direction of run.
