A plane going 300 miles per hour is going 440 feet per second. (300 * 5280 / 60 / 60) In four hours, it will have traveled 1,200 miles, or 6,336,000 feet.
73.33 feet per second.
100 miles per hour = [ 146 and 2/3 ] feet per second. (You don't need to know how long the speed lasted in order to know the speed.)
75 miles per hour = 110 feet per second
85.0666667 feet per second
16.5 feet per second.
(171 miles / 3 hours) x (5,280 feet / mile) x (1 hour / 3,600 seconds) = 83.6 feet/second
42 miles = 221760 feet 3 hours = 10800 seconds 42 miles in 3 hours = 221760/10800 = 20.533 feet pe second

17.6 feet/second*60 seconds/minute*60 minutes/hour=63360 feet per hour there are 5280 feet in a mile 63360 feet/hour*mile/5280 feet=12 miles per hour 90 miles/12 miles per hour=7.5 hours
miles (M) * 5280 = feet (D) hours * 3600 = seconds. (T) So D / T = or M * 5280/3600 . . . . . . . . . . 67.7 Miles per Hour = 99.29333333333332 Feet per Second
