Question

The diameter of a bullock cart wheel is 2.1m how many times must the wheel rotate
for the cart to cover a
distance of 3.3km
a) 0.5 b)5
C) 50 D)500
​

Answer 1

Step-by-step explanation:

Answer

Diameter of cart =1.4m

Circumference =πd=722×1.4

                                    =22×0.2

                                   =4.4 metres

1 rotation of the wheel travels 4.4 metres.

Total distance to travel =1.1km =1100m

No. of rotations required =4.41100=4411000=250

The wheel completes 250 rotations to reach 1.1km.
