Question

A car travels at 20 meters per second.

What is its rate in kilometers per hour?

Answer 1

I don't know if you know this, but we multiply it by 18/5 to convert into km/h

Answer 2

\( \color{Black}{\Rightarrow \Large {20 } \cdot {18 \over 5}}\)

Answer 3

@shubham.bagrecha I believe something is wrong with that

Answer 4

\( \color{Black}{\Rightarrow 4 \cdot 18}\)
after cancelling ^

Answer 5

Metre/Second is given..

To convert Metre into Kilometre, we divide it by 1000

And to convert Second into Hour, we divide it by 3600

So, Meter/Second = (1/1000)/(1/3600) Kilometer/Hour

So, Meter/Second = 3600/1000 = 36/10 = 18/5 Kilometer/Second

So, simply you can multiply the given with 18/5 to get the desired result..
