Question

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

Answer 1

Answer:

breadth=120m=120/1000km=0.12km

length=180m=180/1000km=0.18km

Perimeter rectangular Park=2(l+b)

=2(0.12+0.18)=2×0.3=0.6km

distance covered in 5 rounds=5×0.6=3km

time=total distance/speed=3/7.5=2/5hour=2/5×60min=24min

Step-by-step explanation:

answer:24minute
