Question

Friends!
Help!!
Give reasons :-
(i) The local time is practically impossible to follow.
(ii) IST is 5½hours ahead of GMT.

Answer 1

every country has its own time zones according to 24 time zones India has its own time zone that is IST India lies in the latitude 82 1/2"30"east at Uttar Pradesh. so we need to move towards India's latitude from the GMT. if a person move from one latitude to other latitude the time at the next latitude will be greater by 4 minutes so if you calculate from the GMT to India's latitude it would be fine half hours so we had 5 and half hours to GMT to get the actual time in Indian Standard Time that is ist =GMT+5 1/2 hrs

Answer 2

1.)

Because time varies place to place.

For Example :-

Kisi passenger ko Delhi se Jaipur jana hai, vah train pe 6 : 00 baje baita aur use 8 : 00 baje Delhi pahuchna tha, par jab vah Delhi pahucha toh usne dekha ki 9 : 00 baje the kyuki jab Jaipur mein 8 : 00 time hota hai toh Delhi mein 9:00 bajte hai.

Isliye local time ka use impossible hai.

2.)

Distance between India and GMT in degrees is 82.5

And we know that,

1° = 4 minutes

=> 82.5° = 4 × 82.5 minutes

= 330 minutes

= 6 hours 30 minutes
