Question

Small cart is being driven at 10 kilometre per hour if each wheel is 91 cm in diameter find the number of revolutions made by each wheel per minute

Answer 1

Answer:

Speed of the cart = 10km/hr

= 10×1000/60 m/ min = 1000/6 m/min.

Diameter of the wheel = 91 cm= 0.91 m

Radius of the wheel = 0.91/2 m

Circumference of the wheel= 2πr

= 2 × (22/7) × (0.91/2) m= 22×0.13 m

No.of revolutions per minute= (1000/6)/(22×o.13) = 1000×100/(6×22×13)

= 1000×25/429
