49. Track and Field A person who runs the 100-yard dash in
10.5 seconds has an average speed of 9.52 yards/second.
Convert 9.52 yards/second to miles/hour. (Round to the
nearest tenth.)

Respuesta :

9.52 yards per second is equal to 19.47273 miles per hour

Solution:

Given that, we have to convert 9.52 yards/second to miles/hour

Use the following conversion factor,

[tex]1\ yard = \frac{1}{1760}\ miles\\\\1\ second = \frac{1}{3600}\ hour[/tex]

Therefore,

[tex]\frac{1\ yard}{1\ second} = \frac{3600\ miles}{1760\ hour} = 2.04545 \frac{miles}{hour}[/tex]

Convert 9.52 yards/second to miles/hour

[tex]9.52\ \frac{yard}{second} = 2.04545 \times 9.52\ \frac{miles}{hour}\\\\9.52\ \frac{yard}{second} = 19.47273\ \frac{miles}{hour}[/tex]

Thus, 9.52 yards per second is equal to 19.47273 miles per hour
