Question

the diameter of of the wheel of a bus is 1.4 meter. if the speed of the bus is 66 km/hr, then find the number of resolution taken by wheel in one minute?​

Answer 1

Answer:

250 revolution

Step-by-step explanation:

Circumference = No.of revolutions * Distance covered

Distance to be covered in 1 min. = (66 X1000)/60 m = 1100 m.

Circumference of the wheel = 2 x (22/7) x 0.70 m = 4.4 m.

Number of revolutions per min. =(1100/4.4) = 250.
