Question

Answer in brief:
(a) If it is 12 noon at 60°E longitude, then
explain what would be the time at
30° w longitude?​

Answer 1

Explanation:

First we have to find the difference in degrees between the two points, this gives (60+30)=90

,(hint:east and west longitudes, you add). Also we know that 1 degree is equivalent to 4 minutes.

Converting the difference in degrees between the two points into minutes gives, 90 by 4 which is equal to 360 minutes. 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.
