1 mile per minute equals how many miles per hour?

• A. 1 mile per hour
• B. 30 miles per hour
• C. 60 miles per hour
• D. 120 miles per hour

Answer: (C)

Converting time units is the idea here. There are 60 minutes in an hour, so multiply the speed by 60 to go from per minute to per hour. 1 mile per minute × 60 minutes per hour = 60 miles per hour. In terms of intuition, at 60 mph you’d cover 60 miles in one hour, which is the same as traveling one mile each minute. (For reference, 30 mph would be 0.5 miles per minute, and 120 mph would be 2 miles per minute.)
