Question

Nagma runs around a rectangular Park 180 M long and 120m wide at the rate of 7.5 km per hour in how much time will she complete 5. round

Answer 1

speed of nagma = 7.5km/hr = 2.08 m/s
dimensions of rectangular park=
l= 180 metre
b = 120 metre
number of rounds she has taken= 5
therefor distance she covered area = l*b*no of rounds
=180*120*5= 108000
speed of nagma = distance/time
2.08=108000/t
t=108000/2.08
t= 51923.0769
