Question #87525

you are aboard a boat that has two stopwatches. One gives you the universal time of 15h and the other the local time of 9h. If your latitude was calculated at 62 degrees north What is your longitude?

Expert's answer

Difference in time is equal to 15h-9h=6h

Since there are 24 hours in a day and 360 degrees in a circle, the sun moves across the sky at a rate of 15 degrees per hour (360° ÷ 24 hours = 15° per hour).

In this case, person is near 90° longitude (6 hours × 15° per hour = 90°).

If your latitude was calculated at 62 degrees north and the universal time ahead of the local time then longitude is 90° eastern longitude.

Answer:

90° eastern longitude
