1. Convert miles to feet:
* There are 5280 feet in one mile.
* So, 140 miles is equal to 140 * 5280 = 739,200 feet
2. Convert hours to seconds:
* There are 3600 seconds in one hour (60 minutes * 60 seconds).
3. Calculate the speed in feet per second:
* Divide the distance in feet (739,200) by the time in seconds (3600):
739,200 feet / 3600 seconds = 205.33 feet per second
Therefore, a car traveling at 140 miles per hour is going approximately 205.33 feet per second.
