Question

Convert 4 m/h to cm/min

Answer 1

`\text{6.67 cm/min}`

Step-by-step explanation

We want to convert 4 metres per hour to centimetres per minute.

To do that, we have that 4 m/h means:

`\frac{4\text{ metres}}{1\text{ hour}}`

So, to convert to centimetres per minute, we convert the numerator to centimetres and convert the denominator to minutes:

`\begin{gathered} 1\text{ metre = 100 centimetres} \\ 1\text{ hour = 60 minutes} \\ \Rightarrow\text{ }\frac{4\cdot\text{ 100 centimetres}}{1\cdot\text{ 60 minutes}} \\ \Rightarrow\text{ 6.67 cm/min} \end{gathered}`
