Question

22.5 m/s to km/h please answer fast I plead you

Answer 1

Answer:

22.5 m/s is 81 km/h

The formula to be used is

Multiply the value of speed in (m/s) with 18 and divide the whole thing by 5

OR

Multiply the speed value by 3.6

Therefore,

22.5 * 3.6 = 81

22.5 m/s is 81 km/h

Answer 2

SOME IMPORTANT CONVERSIONS TO REMEMBER

• 1 hour = 3600 seconds
• 1 minute = 60 seconds
• 1 hour = 60 minutes
• 1 km = 1000 m

Given

22.5 m/s

First convert 22.5 into a fractional form

$\implies 22.5 = \dfrac{225}{10} = \dfrac{45}{2}$

To convert m/s to km/h, multiply it by 5/18

$\implies \dfrac{45}{2} * \dfrac{18}{5}$

$\implies 9 * 9\\\\\implies \boxed{\boxed{\bold{ 81 km/h}}}}}$

NOTE

• To convert km/h to m/s, multiply it by 5/18
