You need to know the conversion rates for both miles to feet AND hours to seconds. There are 5280 feet in a mile and 3600 seconds in an hour.
90mi/1hr (5280 ft/mi)(hr/3600 s)
You want the units to cancel out, so that's how you decide to put mi and hr in the numerator or the denominator. For miles to cancel out, it has to be in the denominator of the conversion factor and vice versa for hours. After the units cancel out, you're left with:
(90)(5280 ft)/(3600 s) = 475200 ft/3600 s = 132 ft/s
First, convert the hours to seconds:10 miles/hour x 1 hour/3600 seconds = .002777 miles/secondNext, convert the miles to feet:.002777 miles/second x 5280 feet/mile = 14.67 feet/second
Assuming the question is refering to feet PER second and miles PER hour, 176 fps = 120 mph
Miles per hour x 1.467 = feet per second.
66 feet per second = 45 mph.
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 miles per hour to feet per second multiply by 5280 (feet in a mile) and then divide by 3600 (seconds in an hour).
First, convert the hours to seconds:10 miles/hour x 1 hour/3600 seconds = .002777 miles/secondNext, convert the miles to feet:.002777 miles/second x 5280 feet/mile = 14.67 feet/second
Assuming the question is refering to feet PER second and miles PER hour, 176 fps = 120 mph
Miles per hour x 1.467 = feet per second.
To convert feet per second to miles per hour, you can use the conversion factor of 1 foot per second is approximately 0.6818 miles per hour. You can multiply the value in feet per second by 0.6818 to get the equivalent value in miles per hour.
877 feet per second = 598 mph
66 feet per second = 45 mph.
There are 3,600 seconds in an hour (60 seconds / minute * 60 minutes / hour). There are 5,280 feet in a mile. Therefore to convert feet / second into miles per hour, multiply by 3,600 / 5,280 (0.68) So 88 feet per second is 60 miles per hour. To go the other way (convert from miles per hour to feet per second), divide by 0.68.
To convert 15 miles per hour to feet per second, you would multiply 15 by 5280 (the number of feet in a mile) and then divide by 3600 (the number of seconds in an hour). This gives you approximately 22 feet per second.
To convert miles per hour to feet per second, you need to multiply by 1.4667. Therefore, a car traveling at 140 miles per hour is moving at approximately 205.33 feet per second.
To convert feet to miles, divide by 5280 (1 mile = 5280 feet). To convert hours to miles per hour, divide distance in miles by time in hours. Thus, to convert 30000 feet to miles per hour, first convert feet to miles (30000/5280), then divide by the number of hours to get miles per hour.
To convert 240 miles per hour to feet per second, first convert miles to feet by multiplying by 5280 (since 1 mile = 5280 feet). Then convert hours to seconds by multiplying by 3600 (since 1 hour = 3600 seconds). Finally, divide the distance in feet by the time in seconds to get the speed in feet per second.
