Question

Express each of the following speeds in km/h.

(c) 90 m per minute​

Answer 1

Step-by-step explanation:

90=x×1000÷3600

90×3600÷1000=x

x=324

Answer 2

Answer:

To convert m to km we divide the value by 1000 and to convert minute to hour we divide the value by 60.

So we can write it as

= 90 × (1/1000)/(1/60) km /hr

= 90×60/1000

= 5.4 km /hr

Hope it helps..
