Question

16. The radius of the wheel of a bus is 0.56 m. If the wheel rotates 250 times a minute, find the speed of the bus in kmph.​

Answer 1

Answer:

52.8 Kmph

Step-by-step explanation:

Let us first find the distance covered by the bus

2 x 0.56 x 22/7 x 250

When we solve this we get 880 meters

In a minute there are 60 seconds

Therefore the speed in mps (meters per second) is 880/60

When we reduce it is 44/3

Let us now convert this in Kmph 44/3 x 3600/1000

When solved 52.8 kmph
