Ravi walks at a uniform speed of 4 km per hour.How much time does he take to cover 600 metres

I want answer in step by step ​

Answer 1

Answer:

It takes 0.15 hours in 600 meters.

Step-by-step explanation:

Ravi walks 4km in 1 hour

So,

Here 1000m =  1 km

Therefore,

⇒ He walks 1000 × 4 m in 1 hour

⇒ He travels 1 m in  (1 ÷ 4000 ) hour

⇒ He travels 600m in (1×600) /4000 hour

⇒ He travels 600 m in 0.15 hours.

Answer 2

Answer:

Step-by-step explanation:

Step 1 - Convert the speed into m/s

⇒ 4km/h = 4000/3600 = 10/9 m/s

Step 2 - Ravi covers 10/9 m in 1 sec

⇒ 600m will be covered in 600 × 9/10 = 540 seconds, i.e 9 minutes

Step - 3 Final answer:- Ravi covers 600 metres in 9 minutes
