Work Step by Step

This question asks us for a complete unit conversion from 344 m/s to mph. There are a number of conversions to do to complete this. The entire calculation is $\frac{344 meters}{1second}$$\times$ $\frac{.0006213 miles}{1 meter}$$\times$ $\frac{60 seconds}{1 minute}$$\times$ $\frac{60 minutes}{1 hour}$. This conversion will bring m/s to mph. First you mutiply across the top and bottom separately, and then you divide the top by the bottom. This results in an answer of about 770 mph, which is correct.
