what do they give the speed of the space shuttle in orbit is about 17000 ft per second how many miles per hour does the shuttle travel ?

We are asked to convert 17000 feet per second to miles per hour
[tex]\frac{17000\text{ fe}et}{s}\times\frac{0.000189394\text{miles}}{1\text{ foot}}\times\frac{3600s}{1hr}[/tex][tex]\approx11590.91\frac{miles}{hr}\text{ }[/tex]
