Continue ReadingMultiplying 300 fps by the factor 0.68182 mph/1.0 fps gives the answer 204.55 mph. If students do not know this conversion factor, then the answer is also found by using the facts that 1.0 hour is equal to 3,600 seconds and 1.0 mile is equal to 5,280 feet. The calculation for finding the answer is 300 feet/second x 3,600 seconds/ 1.0 hour x 1.0 mile/5,280 feet.
