Answer:

about 946.2 mph

Explanation:

You want the speed in mph of a bullet that travels 423.0 m/s.

Conversion

The conversion of units involves multiplying by fractions that cancel the units you have and leave the units you want. Each fraction has its numerator equal to its denominator.


423.0\text{ m/s}*\frac{1\text{ mi}}{1609.344\text{ m}}*\frac{3600\text{ s}}{1\text{ h}}\approx\boxed{946.2\text{ mi/h}}
