Question

The wheel of a bullock cart has a diameter of 1.4 M how many rotation in will the wheel complete as the car travel 1.1 km

Answer 1

250 rotations is the answer

Answer 2

Answer:

250

Step-by-step explanation:

The wheel of a bullock cart has a diameter of 1.4 m

Radius = 1.4/2 = 0.7 m

Circumference of wheel = 2πr

                                         =2 *3.14*0.7

                                         = 4.396 m

So, distance traveled in 1 rotation =4.396 m

Now , to calculate how many rotation in will the wheel complete as the car travel 1.1 km

1 km = 1000 m

So, 1.1 km = 1100 m

No. of rotations in 4.396 m = 1

No. of rotations in 1 m = 1/4.396

No. of rotations in 1100 m = (1/4.396)*1100

                                            = 250.2274

So, the wheel will complete 250 rotations to travel 1.1 km
