0.15. The diameter of the wheel of a vehicle is 1.4 m. How many rotations will the wheel completein travelling a distance of 2.2 km?Solution:​

Given :

• The diameter of the wheel of a vehicle is 1.4 m.

To find :

• How many rotations will the wheel completein travelling a distance of 2.2 km ?

Solution :

• Diameter of wheel = 1.4 m
• Radius of wheel = 1.4/2 = 0.7m

The rotations will the wheel complete in travelling a distance of 2.2 km

• 2.2km = 2.2 × 1000 = 2200 m

500 rotations will the wheel complete in travelling a distance of 2.2km
