Feet sec. or per minute? Need more info to answer.
60 mph = 88 fps (exactly)
Use this formula: feet per second x 0.6818 = miles per hour:325 ft/sec x 0.6818 = about 221.6 miles per hour
There are 5,280 feet per mile and 3,600 seconds per hour. Therefore, 5280 X 240 = 1,267,200 feet and 1,267,200/3,600 = 352 feet per second.
Conversion: miles per hour x 0.00044704 = km/sec

Use this formula: feet per second x 0.6818 = miles per hour:325 ft/sec x 0.6818 = about 221.6 miles per hour
To convert feet per second to miles per hour, first convert feet to miles. There are 5280 feet in a mile. So, 8.5 feet per second = 8.5 * 3600 seconds in an hour / 5280 feet in a mile = 5.78 miles per hour.
(mph x 1.466 = feet per second). So, 70 mph x 1.466 = 102.62 feet per second.
Multiply by time. ft3 / sec * sec = ft3
There are 5,280 feet per mile and 3,600 seconds per hour. Therefore, 5280 X 240 = 1,267,200 feet and 1,267,200/3,600 = 352 feet per second.
To convert 750 miles per hour to inches per second, you can use the conversion factors: 1 mile = 63,360 inches, and 1 hour = 3,600 seconds. Therefore, 750 miles per hour is equal to (750 * 63,360) / 3,600 inches per second.
Multiply (meters/sec) by 3.28084 to get (feet/sec). (rounded)If you don't need it that close, multiply by 3.28 .
Two miles per minute.
40 mph = 58.66... feet per sec
Conversion: miles per hour x 0.00044704 = km/sec
