If your ground speed is 60 knots, what is your speed in miles per minute (MPM)?

If your ground speed is 60 knots, what is your speed in miles per minute (MPM)?

• A. 1.0 MPM
• B. 0.5 MPM
• C. 1.5 MPM
• D. 2.0 MPM

Answer: (A)

Ground speed in knots is nautical miles per hour. To get miles per minute, see how far you travel in one minute. At 60 knots you cover 60 nautical miles in one hour. There are 60 minutes in an hour, so in one minute you go 60/60 = 1 nautical mile. In this context, miles per minute (MPM) corresponds to nautical miles per minute, so the speed is 1.0 MPM. The other values would imply different hourly speeds (0.5 MPM would be 30 NM/hour, 1.5 MPM would be 90 NM/hour, 2.0 MPM would be 120 NM/hour). A quick check: 60 NM in 60 minutes means 1 NM per minute, confirming 1.0 MPM.
