Question

If the time required to complete two rounds on a circular track is 2 hours and 20 minutes, find the minutes required to complete one round on the same circular track.

• A. 70

Answer 1

The correct option is A 70
Time required to complete two rounds on a circular track = 2 hours and 20 minutes

We know that 1 hour = 60 minutes

So, time required to complete two rounds on a circular track = 2 $\times$ 60 $+$ 20 = 140 minutes

Time required to complete one round on the circular track = $\frac{140}{2}$ = 70 minutes
