Question

an athlete covers a distance of 0.4 km in completing one round . how many rounds does he make if he runs a total of 8.4 km distance ?

Answer 1

21 rounds

Explanation:

`1`
`round = 0.4km`

`Total`
`distance = 8.4km`

`8.4/0.4`

`=21`

Answer 2

Given:

• Total distance covered= 8.4 km
• Distance covered in 1 round= 0.4 km

To find:

The number of rounds he makes, if he runs a total of 8.4 km distance.

Solution:

`\large\boxed{R=(Total \: distance)/(Distance \: covered \: in \: 1 \: round)}`

So, we'll have to divide the total distance covered by distance covered in 1 round.

Let's substitute according to the formula.

`R= (8.4)/(0.4)`

= 21 rounds

Hence, the number of rounds he makes, if he runs a total of 8.4 km distance is 21
