Question

The circumference of the wheel of a truck is 1 meter.to cover a distance of 1.5 km.the number of revolutions made by the wheel are:

Answer 1

1500 because 1 meter is 1 revolution so 1.5km is 1500m means 1500 revolutions

Answer 2

The number of revolutions can be made by wheel to cover the distance 1.5 km is 1500

Given:

The circumference of the wheel of a truck is 1 meter

To find:

Number of revolutions must be made by wheel to cover the distance 1.5 meter

Solutions:

Given that circumference of wheel is 1 meter

Here the distance can covered by wheel

= number of revolutions × circumference of wheel

Let x be the number of revolutions made by wheel to cover 1.5 km

⇒ 1.5 km = x (1 meter)

⇒ 1500 meter = x meter  [ ∵ 1 km = 1000 meters  ]  

⇒ x = 1500  

The number of revolutions need to cover the distance 1.5 km is 1500
