Question

What is the time at place x located at 20°E longitude when it is 2 PM at place

Answer 1

Answer:

Explanation:

At B which is at 40 degree west longitude, the time can be located in this way…

We know that 1 degree = 4 minutes

From the prime meridian I.e 0 degree, time decreases westward and increases eastward.

If the time at 60 degree East longitude is 5 pm then at 40 degree West it will be-

60 degree E + 40 degree W = Difference of longitude is 100 degree.

We know 1 degree = 4 min.,

And we know that time decreases when we move from East to West longitude

So 100 degree = 4×100= 400 minute or 6 hours 40 minutes.

So 5PM - 400 minutes= 5 PM - 6 hr 40 minutes =10:20 AM is the right time at the place B.

So, far as place is concerned, you will have to see the map to know the exact location of that place according to that longitude.
