Question

If Shyam runs at a speed 20 km/hr. How long will he take to run a 800 metre race ?​

Answer 1

He will take 10 minutes to cover 800 metres

Answer 2

Answer:

2.4 minutes

Step-by-step explanation:

First we need to work on same units so converting the distance from metres to km we get 0.8km

Now we know that speed = distance/ time

time= distance/speed

Therefore time taken by him to run a 800 metre race is

0.8/20 = 0.04 hours We know that 1 hour = 60 mine

Therefore 0.04 hours will be 0.04 x 60 minutes

2.4 minutes.
