If the difference in time between, two places were 2 hours and 20 minutes, then the difference in their longitudes would be ________

If the difference in time between, two places were 2 hours and 20 minutes, then the difference in their longitudes would be 35°. The time difference between each longitude (each degree) is 4 minutes. So if it is 12 noon at Greenwich (0°), it would be 12:04 pm at 1° meridian and so on.
