The earth rotates 360o of longitude every 24 hours, so it takes 24 ÷ 360 hours to rotate 1o of longitude:
24 ÷ 360 hours = 24/360 hours
= 1/15 hours
= 1/15 x 60 minutes
= 4 minutes
The sun will cross 1o of longitude in the same time that the earth takes to rotate 1o of longitude, namely 4 minutes.

The hour hand of a clock completes a full revolution every 12 hours, which is equivalent to 720 minutes. Therefore, to calculate how many minutes it takes for the hour hand to rotate through one degree, you divide 720 minutes by 360 degrees, giving you 2 minutes per degree.
If it takes 39 minutes to travel 2.7 miles it will take 14 minutes 26 seconds to travel one mile.
"60 mph" means 60 miles in 60 minutes. At that speed . . . -- 1 mile takes 1 minute -- 1.2 miles takes 1.2 minutes -- 37 miles takes 37 minutes etc.
It depends on the speed. At 60 miles per hour it takes 50 minutes. At 30 miles per hour it takes 100 minutes
