Question

The longitude of Allahabad, India is 81° 50' (81 degrees, 50 minutes) E. If the time in Allahabad is around 12 noon, what time of the day would it be, at a place whose longitude is 10°W?
a)sunrise
b)sunset
b)noon
d)midnight

Answer 1

Answer:

Sunrise

Explanation:

As there is roughly a westward change in longitude by 90°, accordingly the local time at 10°W, will lag behind by about 6 (=90/50) hours. Hence it will be Sunrise there. Hence (A) will be the correct answer.

But whether the sun will rise there at 6 A.M. or not, will depend on the latitude of the place and the month of the year.
