Question

while the sun rises earlier in the east, say nagaland and also sets earlier, how do the watches at Kohima and new delhi show the time? Why the western coastal plain is devoid of any delta?​

Answer 1

Answer:

The large longitudinal expanse of India about 30° approximately. So even when the sun is still shining in the western coast, it is already night in the northeast. Hence, we need two or three time zones to clearly reflect diurnal changes. ... The latitudinal extent of India is 3214 km from north to south.
