A circular running path is 1452 m in circumference. Two men start from the same point and walk in opposite directions at speeds of 7.5 km/h and 9 km/h, respectively. When will they meet for the first time?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 5.28 min.
Relative speed of two men = 7.5 + 9 = 16.5 km/h
Distance = Speed × Time
⇒ 1452 = × Time
⇒ Time = 316.8 sec
⇒ Time taken by them to meet each other = = 5.28 min
