Question

calculate time on the logitude 55 degrees east when it is noon at Greenwich. please explain ​

Answer 1

Answer:

clock will be showing 03 hrs 40 minute afternoon

Explanation:

for 1 rotatation  i.e 360 degree= 24 hr

hence for             1 5 degree = 1 hr              

                            for 1 degree =  60 min/15      ( as 1hr = 60 min )    

                            for 1 degree = 4 min

for 55 degree ,     55*4=220 min

                               i.e  220/60= 3 hr 40 min    ( as 1hr = 60 min )

as green which time  is at 0 degree , as we move east time will advance.

at noon in green which it will be 12.00 hrs .

no to get the time at 55 degree add 3 hr and 40 min to 12.00 hrs

it will come = 3 o clock and 40 mins in afternoon.
