Question

A park is 1500 metres long and 750 metres wide. A cyclist has to take four rounds of this park how much time with be take at the speed of 4.5km/hr

Answer 1

Step-by-step explanation:

Length of the park = 1500 m

Breadth of the park = 750 m

Perimeter of the park = 2(l+b) = 2(1500+750) = 4500 m

Perimeter of the park for 4 rounds = 4500×4 = 18000 m

Speed = 4.5 km/hr = 45/10 km/hr = 45/10×5/18=5/4 m/s

Time = Distance = 18000×5 = 22500 seconds

Speed 4
