Final answer:
To convert 146.7 feet per second to mph, multiply by 3600 and divide by 5280. Doing this yields a result of approximately 100.0 mph, meaning the correct answer is C) 100.1 mph.
Explanation:
To convert speed from feet per second (ft/s) to miles per hour (mph), you need to understand the relationships between these units. One mile equals to 5280 feet and one hour is equal to 3600 seconds. Therefore, to convert feet per second to mph, you multiply the speed in ft/s by 3600 seconds/hour, and then divide by 5280 feet/mile.
Let's do the calculation for 146.7 ft/s:
Speed in mph = (146.7 ft/s * 3600 s/hr) / 5280 ft/mile
After doing the math, we got about 100.0 mph; thus, the closest answer choice is C) 100.1 mph.
