A, B and C runs at speeds 5 m/s, 3 m/s and 8 m/s, respectively. They start the race at the same time from the same point. After some time, it was found that the distance between A and C is 6m. Determine the distance between A and B.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 4 m.
Speed is directly proportional to distance.
Ratio of speed = Distance = A : B : C = 5 : 3 : 8
A - C = 6 m
⇒ 8 - 5 = 6
⇒ 1 = 2
So, A - B = (5 - 3) × 2 = 4
