$\mathfrak { \large{\underline {\underline{Explanation \: : - }}}}$

Dehli = 79° 35' E

GMT = 10 : 00 AM

We know that,

1° = 4 minutes

79° = 79 × 4 = 316 minutes

= 5 hours 16 minutes

60' = 1°

35' = 1/60 × 35

= 140 seconds

= 2 minutes 20 seconds

5 hours 16 minutes + 2 minutes 20 seconds

= 5 hours 18 minutes 20 seconds

10 : 00 : 00

+ 9 : 18 : 20

=========

15 : 18 : 20

=========

Dehli will have 3 : 18 : 20 P.M. as its Local Time.

Answer 2

Explanation:

At GMT the time is 10: 00AM

i.e at 0° the time is 10: 00AM

1° = 4 minutes

79° = 79 × 4 = 316minutes

= 5hours 30 minutes

35' = 35 minutes

5hours 30minutes+ 35 minutes

= 6hours 5 minutes

Time at 79°35' is 10:00 AM + 6hours 5 minutes

= 4: 05PM
