Answer 2

Hello friend

Here's your answer

When we want something in kms to be converted to metres then we multiply it with 1000

When we want to convert hour into seconds then we multiply it with 60×60=3600

Km/he when to be converted into hour then we need to multiply it with 1000/3600=5/18

In the same way to convert 54km/he into m/sec we need to multiply it with 5/18

54×5/18

=3×5

=15m/s

(When u want to convert m/sec into km /h then multiply it with 18/5)

Hope it helps!
