Answer 1

Answer:

Option (1)

Step-by-step explanation:

Fastest time recorded = 50 yards dash is 5.2 seconds.

To convert this time into the rate of miles per hour, expression to be used will be,

$\frac{50\text{yd}}{5.2\text{sec}}\times \frac{3\text{ft}}{1\text{yd}}\times \frac{1\text{ mile}}{5280\text{ft}}\times \frac{60\text{sec}}{1\text{min}}\times \frac{60\text{min}}{1\text{hr}}$

By cancelling common term in the numerator and denominator in the given expression we will get the answer in miles per hour.

Therefore, Option (1) will be the correct option.
