The jogging track in a sports complex is 76 metres in circumference. Sanjay and his wife start from the same point and walk in opposite directions at 4.5 km/hr and 3.75 km/hr respectively. They will meet for the first time in:

6 min.
5.5 min.
5.28 min.
4.9 min.

Validate

Solution:

Their relative velocity = 4.5 + 3.75 = 8.25 km/hr
It is clear that they will meet, when they are 726 m apart
Hence, they will meet after =

{726}/{1000} × 1/{8.25}

hr =

{726}/{8250} × 60

min = 5.28 min
