Question

. If Delhi is located almost at 77030’ east longitude then what will be the difference between its local and standard time.​

Answer 1

Explanation:

if delhi is located almost 77 degrees 30' east longitude,

1 °  = 4 minutes

77 ° 30' = 77.5°

77.5° * 4 =   310  minutes

= 5 hr 10  minutes

this mean local time will  be 5 hr 10 minutes  ahead of GMT

Standard time is  5 hr 30  minutes ahead of GMT

Local time will be  20 minutes behind standard time  

hope it helps
