Question

1. 10°East is 12:40 pm find time along 10°west 2. time along 40° east is 7:40 am find time along 15° east

Answer 1

Answer:

1. 11:20 am

2. 6:00am

Explanation:

1.=》At 10°east the time is 12:40,

And we know that 1° = 4minutes

So, At 0° the time will be =>

12:40 - 40 = 12:00.

We know that time in the west runs a little behind the time in the east.

So, At 10°west the time will be=>

12:00 - 40 = 11:20.

2.=》 Time along 40°east is 7:40am.

Now we have to know how much difference is there between 15°east and 40°east=>

40° - 15° = 25°,

So,the difference is 25°,

We already know that 1 latitude = 4minutes,

25× 4 = 100minutes

So the difference between their time is 100minutes.

So,time along 15°east will be =>

7:40 - 100 = 6:00.
