Multiply by one (1)

$\dfrac{58\;mile}{hour}\cdot\dfrac{5280\;ft}{1\;mile}\cdot\dfrac{1\;hour}{3600\;sec}$

anonymous · Answer

$$58 \frac{miles}{hour}$$ since 1mile = 5280 feet and 1hour = 60² seconds you just replace one for the other since they are equal: $$58 \frac{mile}{hour} = 58 \frac{5280 feet}{60^{2} seconds} = \frac{58*5280}{3600}\frac{feet}{seconds}$$ which is 85.06ft/s
