Answer:
To convert m/sec to km/h the factor is 3.6
The speed of the airplane is [tex]216\frac{km}{h}[/tex]
Step-by-step explanation:
we know that
[tex]1\ km=1,000\ m\\1\ h=3,600\ sec[/tex]
so
[tex]60\frac{m}{sec}=60\frac{(1/1,000)}{(1/3,600)}=60\frac{3,600}{1,000}=216\frac{km}{h}[/tex]
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
