Question

A park is 2000 meters long and 1500 meters
wide . A cyclist has to take four rounds of this park . How much time he will take at speed of 7km/h?
​

Answer 1

Step-by-step explanation:

Perimeter of rectangular park=2(l+b)=2(2+1.5)=2*3.5=7km

1round distance =7km

4 round distance=28km

Time taken =distance /speed=28/7=4h

Answer 2

4hours is the time taken by cyclist.

perimeter of park=2(l+b)

=2(3500m)=7000m

total distance after covering 4 rounds =28000m

as we know time = distance/speed

28000m=28 km

28 km / 7 km per hour

4 hour. answer
