Question

2.57 mi/hr= how many m/min? Simplify your answer, round to the nearest tenth.

Answer 1

Let's convert the units, to do this we need to cancel the original units to get the units we want; we achieve this the following way:

`2.57\frac{\text{ mi}}{\text{ hr}}\cdot\frac{1609.34\text{ m}}{1\text{ mi}}\cdot\frac{1\text{ hr}}{60\text{ min}}=68.9\frac{\text{ m}}{\text{ min}}`

Therefore 2.57 mi/hr is the same as 68.9 m/min.
