Answer 1

Answer:

Every 1° is equal to 4 minutes.

If it is on west of Greenwich meridian, than substract the calculated time from actual time of GMT and if it is on east, then add.

A) Mumbai

78°E = 78×4 = 312 minutes

312min = 5 hours 12 minutes.

12:00 + 5hr 12min = 05:12 pm

B) Sydney

150°E = 150×4 = 600 minutes

600min = 10 hours.

12:00 + 10hr = 10:00 pm

C) Chicago

90°W = 90×4 = 360 minutes

360min = 6 hours.

12:00 - 6hr = 06:00 am.
