Question

What would be the time at 90 degree east longitude if it is 12 noon at 30 degree east longitude

Answer 1

Explanation:

Converting the minutes into hours gives 360/60=6 hours, this is because we know that 1 hour =60 minutes, then the time at 30 degrees west will be 12 noon subtract 6hours because it behind the prime meridian, which gives 6 am. Thus time 30 degrees west is 6 am.
