Question

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

Answer 1

Answer:

Step-by-step explanation:

perimeter =2(l+b)

=2(180+120)

=2(300)

=600m

this is for one round

for 5 round =5×600

=3000m

time taken =disatance /speed

=3000/7500

=2/5 m/h

Answer 2

Answer:

Speed of Nagma is 7.5 km/hour. Nagma will complete five rounds in 0.4 hours. We know that 1 hour = 60 minutes. Therefore, Nagma will complete five rounds in 24 minutes
