Question

An airplane is traveling at a speed of 60 meters per second. Identify the correct conversion factor setup required to compute the speed of the airplane in kilometers per hour.

Answer 1

To convert m/sec to km/h the factor is 3.6

The speed of the airplane is
`216(km)/(h)`

Explanation:

we know that

`1\ km=1,000\ m\\1\ h=3,600\ sec`

so

`60(m)/(sec)=60((1/1,000))/((1/3,600))=60(3,600)/(1,000)=216(km)/(h)`

To convert m/sec to km/h the factor is 3.6

That means ----> Multiply the speed in m/sec by 3.6 to obtain the speed in km/h
