Question

If the prime meridian is 5:30a.m. calculate the time at:
A. 10°E B. 15°W C. 40°E D. 50°W​

Answer 1

Answer:

time at A=05:50am B=05:00am C=06:50am D= 03:50am

Explanation:

we know that after the Prime meriidan, there is a longitude at every 15degree seperation and with a time difference of 30mins.

Hence divide the time.30mins by the degrees,15deg inorder to find the min per degree.

so when u do so, its 2mins/deg

hence multiply the required degree and add (if its towards east) and subtract( if its towards west) from the reference time (ie. 05:30am in this case)
