Question

A rate of 4 centimeters per second is equal to how many meters per hour? 4 centimeters per second = meters per hour

Answer 1

4cm/s in m/h
First step, work out how many seconds in an hour
(seconds) 60 x (minutes) 60
60 x 60 = 3600 seconds in an hour
1 seconds = 4 cm
x3600 to get the distance in cm/h
3600 seconds (1 hour) =  14,400cm
Divide by 100 for m/h
14400/100 = 144 meters per hour

Answer 2

The rate of 4 centimeters per second is equal to 144 meters per hour.

What is unit conversion?

A conversion factor is a ratio that expresses how many of one unit are equal to another unit. To convert a smaller unit to a larger unit (eg to ), divide it by the number of smaller units which are needed to make larger unit. To convert from a larger unit to a smaller one, multiply. To convert from a smaller unit to a larger one, divide.

For the given situation,

4 centimeters per second is equal to how many meters per hour.

1 centimeter = $\frac{1}{100} meters$

⇒ $4 centimeter = \frac{4}{100} meters$

⇒$0.04 meters$

1 second = $\frac{1}{3600} hours$

Thus 4 centimeters per second = $\frac{0.04}{1}$ ÷ $\frac{1}{3600}$

⇒ $0.04$ × $3600$

⇒ $144$

Hence we can conclude that the rate of 4 centimeters per second is equal to 144 meters per hour.
