Question

Kyle ran 150 feet and 15 seconds how many hours would it take him to run 30 miles

Answer 1

b. 4.4 hours

Explanation:

We can use the conversion factor 1 mi/h = 22/15 ft/s. The required relation is ...

time = distance/speed

`\frac{30\text{ mi}}{\left(\frac{150\text{ ft}}{15\text{ s}}\right)}*\frac{\left(\frac{22\text{ ft}}{15\text{ s}}\right)}{\left(\frac{1\text{ mi}}{1\text{ h}}\right)}=\frac{(30)(22)\text{\h}}{150}\text{ h}=4.4\text{ h}`

Assuming Kyle can keep up the pace for that distance, it would take him 4.4 hours to run 30 miles.
