Answer 1

Answer:

Answer. = 600 metre or 600/1000 =0.6 kilometre

Answer 2

Answer:

20 metre

Step-by-step explanation:

Firstly convert the km into metre

As we know 1 km = 1000m

Then 72 km = 72000m

Now convert the hour into seconds

Then 1 hour = 60 minutes

And 1 minute = 60 seconds

Therefore 1 hour = 60 × 60 = 3600 seconds

• Speed = Distance

Time

If we want to know the speed of car per second

= 72000

3600

= 20 metre
