Answer 1

Given: The sunset occurs at 7: 15 p.m, the setting time of sun decreases by 30 second everyday.

To find: At what time will the sun set on November 26 in Delhi?

Solution:

• Now we have given that sunset occurs at 7: 15 p.m, the setting time of sun decreases by 30 second everyday.

• Let the number of days be x.

• Now number of days from July 16 to November 26 as calculations will be:

                  x = 15 (jul) + 31 (aug) + 30 (sep) + 31 (oct) + 26 (nov)

                  x = 133 days

• Now we have given that sunset time decreases by 30s everyday, so:

• The change will be:

                   133 × (30)

                   3990 seconds

                  66.5 minutes

• So on 26th November, sun will set at:

                  Sunset time = 7:15 - 66.5

                  Sunset time = 6:08:30 pm

Answer:

             Therefore, sun will set at 6:08:30 pm on 26th November.

Answer 2

Sunset time on November

26th. - 133 * 30 => 3999 seconds

Sunset time = Sunset at _ Sunset time on

July 15 November 26

=>7:15 - 66.5

=>06:08

Therefore the sun set time on November 26 th is 06:08(6h 8min)
