find the time ?

Question

Ekta runs around a rectangular park 180 m long and 120 m wide at the rate of 7.5 km/hr. In how much time she will complete 5 rounds ?

Answer 1

Length of 1 round
= 180m + 180m + 120m + 120m
= 600m

Length of 5 rounds
= 600m * 5
= 3000m
= 3km

Ekta has a speed of 7.5km/hr, so the time taken to run 5 rounds is
= 3km / (7.5km/hr)
= (3 / 7.5) hr
= 6/15 hr
= (6 / 15) * 60 minutes
= 24 minutes
