Step 1

Meter and miles are some common units of distance. Similarly, hours and seconds are units of time. Speed can be defined as the distance travel by the object at a certain time. It is measured in m/sec or miles/hour.

Step 2

Conversion factors are used to convert different units into each other. Conversion factors for the conversion of m/sec to miles/h are:
