4000 fps / 5280 feet per mile = .7575 miles per second
.7575 mps X 3600 seconds per hour = 2727.27 mph
Hilarious! So 4000 feet per minute translates to five times the speed of sound. Sorry. It's 45 mph.
BOTH OF YOU ARE WRONG ITS ACTUALLY 272 MPH

Ask your teacher about length and area...
60 mph = 88 feet per second.
36.67 feet per second.
117.33 feet per second.
40 mph = about 58.6 feet per second.
4000 millimeters = 13.12 feet.
4000 feet = 1.22 km, approx.
4000 kilometers = 13,123,359.6 feet.
1 fathom = 6 feet so 4000 feet = 4000/6 = 666.6667 fathoms.
44 feet per second = 30 mph
37,000 (feet per second) = 25,227.27 mph
55 mph equals 80.66 feet per second
