To convert miles per hour to feet per second, we need to use the conversion factor:
1 mile = 5,280 feet 1 hour = 3,600 seconds
Given: Speed = 850 miles per hour
To convert miles per hour to feet per second, we can perform the following calculations:
Speed in feet per hour = 850 miles/hour × 5,280 feet/mile = 4,488,000 feet/hour
Speed in feet per second = (4,488,000 feet/hour) / (3,600 seconds/hour) = 1,246.67 feet/second (rounded to two decimal places)
Therefore, a speed of 850 miles per hour is approximately equal to 1,246.67 feet per second in a flight.
