Final answer:
A car driving at 35 miles per hour is traveling at approximately 51.333 feet per second, after converting miles to feet and hours to seconds using the factors 1 mile = 5280 feet and 1 hour = 3600 seconds.
Step-by-step explanation:
To convert the car's speed from miles per hour to feet per second, we need to use the appropriate conversion factors. First, we must recognize that 1 mile is equal to 5280 feet. After that, we need to account for the number of seconds in an hour, which is 3600 seconds (60 seconds per minute and 60 minutes per hour).
The conversion process involves multiplying the car's speed in miles per hour (35 mph) by the number of feet in a mile, and then dividing by the number of seconds in an hour:
- Start with the speed in miles per hour: 35 mph.
- Convert miles to feet: 35 miles × 5280 feet/mile = 184800 feet.
- Convert hours to seconds: 184800 feet per hour ÷ 3600 seconds/hour = 51.333 feet per second (approx.).
Therefore, a car driving at 35 miles per hour is traveling at approximately 51.333 feet per second.
