What is the time at 10 degree east when it 4 pm Greenwhich calculate time?

To calculate the time at 10 degrees east when it is 4 pm Greenwich Mean Time (GMT), we need to take into account the time difference caused by the difference in longitude.

10 degrees east is 10/15 = 2/3 hours ahead of GMT.

Therefore, when it is 4 pm GMT, the time at 10 degrees east would be:

4 pm GMT + 2/3 hours = 5:20 pm

So, the time at 10 degrees east when it is 4 pm GMT would be 5:20 pm.
