Question

* One day the weather was very good and a cool breeze was
blowing. He felt so good that he kept jogging till he got tired
after 8 rounds. That day he ran
km and
metres ! the park was 400m long
​

Answer 1

Answer:

boundary of the park=400 metres

round covered by devi=8 rounds

so, 400x8=3200

hence, devi ran 3 km and 200 metres!

Answer 2

The distance he ran is 3 km and 200 m.

Given: Number of rounds ran = 8

Distance of the park = 400 m

To Find: The distance he ran.

Solution:

• The solution can be found using the formula,

The total distance traversed = Distance of the park × number of rounds run

We are given,

Distance of the park = 400 m

The number of rounds ran = 8

So, putting respective values in the formula, we get;

The total distance traversed = Distance of the park × number of rounds run

⇒ Total distance traversed = ( 400 × 8 ) m

                                             = 3200 m

We know that 1000 m = 1 km

∴ 3200 m = 3200 / 1000 km

                = 3.2 km

                = 3 km 200 m

Hence, the distance he ran is 3 km and 200 m.
