- Mumbai is located at 73° E longitude. Kolkata is located at 88° E longitude. Find the difference between the longitudes of these two cities.- If the local time at Mumbai is 3 pm then what would be the local time at Kolkata?

Answer 1

In Kolkata, there will be 2:56 pm. There are total 24 numbers of time zones which can be there in the whole world. If there is each time zone in the 1 hour apart, then there would be 24 in the world.

But the numerous time zones normally have 30-45 minutes difference which only makes the total number of worldwide much higher.

During the daylight saving time, the time changes and the time zone name changes.

Answer 2

The difference between the two longitudes of Kolkata and Mumbai is (88-73)° which is equals to 15°.

The time difference between two adjacent longitudes should be 4 minutes.

Hence the local time at Kolkata will be 2:56 pm.

This is because the space between two adjacent longitudes is always 15° by standard measurement.
