Question

If a bullet travels at 593.0 m/s, what is its speed in miles per hour?

Answer 1

We have $1 \; mile = 1609.34\; meters$. So, $1 \; meter = \frac{1}{1609.34} \;mile$.

$1 \; hour = 3600 \; s$. So $1 \; s = \frac{1}{3600}  \; hour$.

Thus we can convert the units of the given quantity.

That is,

$593\;m/s=593\;\frac{1/1609.34}{1/3600} \;miles/hour\\ 593\;m/s=1,326.51\;miles/hour$.

The quantity is converted to the required units.
