Question

The circumference of a wheel is 125 cm. It rotate on a road at 2 km. How many number rotation?

Answer 1

Solution:-

Given:-

• Circumference of wheel ( Circle ) = 125cm.
• Distance Covered = 2 km

To Find:-

• Number of rotation made by the wheel = ?

Find:-

We know that,

1 km = 100000 cm

=) 2km = 2 × 100000

=) 2km = 200000 cm

Now,

Number of Rotation = Distance Covered/Circumference

=) Number of Rotation = 200000 / 125

=) Number of Rotation = 1600

Hence,

• Number of Rotation made by the wheel is 1600.
