Step-by-step explanation:
Tyrone determines it takes him 58.2 minutes to travel 30 miles to work, then he travels with speed
![\dfrac{30}{58.2}=\dfrac{300}{582}=\dfrac{50}{97}\ \text{miles per minute}.](https://tex.z-dn.net/?f=%5Cdfrac%7B30%7D%7B58.2%7D%3D%5Cdfrac%7B300%7D%7B582%7D%3D%5Cdfrac%7B50%7D%7B97%7D%5C%20%5Ctext%7Bmiles%20per%20minute%7D.)
If 1 mile = 5,280 feet, then his speed is
![\dfrac{50}{97}\cdot 5280=\dfrac{264000}{97}\ \text{feet per minute}.](https://tex.z-dn.net/?f=%5Cdfrac%7B50%7D%7B97%7D%5Ccdot%205280%3D%5Cdfrac%7B264000%7D%7B97%7D%5C%20%5Ctext%7Bfeet%20per%20minute%7D.)
Since 1 minute = 60 seconds, then his speed is
![\dfrac{264000}{97\cdot 60}=\dfrac{4400}{97}\approx 45.36\ \text{feet per second}.](https://tex.z-dn.net/?f=%5Cdfrac%7B264000%7D%7B97%5Ccdot%2060%7D%3D%5Cdfrac%7B4400%7D%7B97%7D%5Capprox%2045.36%5C%20%5Ctext%7Bfeet%20per%20second%7D.)
