Answer 1

It is given in the question that

A projectile is fired at 657 mi/hr. how fast is that in meters per second? use the conversion factor 1 mile = 1610 m.

So we need to convert miles per hour to meters per second.

And it is given that 1 mile  equals to 1610 meters and 1 hour equal to 3600 seconds.

So we will get

$657mi/hour = \frac{657*1610}{3600} m/seconds = 293.825m/s$
