1.	The bicycle travelling?14. A small cart is being driven at 10 km per hour. Ifeach wheel is 91 cm in diameter, find the number ofrevolutions made by each wheel per minute.
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

The bicycle travelling?14. A small cart is being driven at 10 km per hour. Ifeach wheel is 91 cm in diameter, find the number ofrevolutions made by each wheel per minute.

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

The bicycle travelling?14. A small cart is being driven at 10 km per hour. Ifeach wheel is 91 cm in diameter, find the number ofrevolutions made by each wheel per minute.​

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
