Question

The time at GMT is 4pm. Find out the local time for 75degree west.

Answer 1

Answer:

The lengths of two adjacent sides of parallelogram are 51cm and 37cm respectively. One of its diagnols is 20cm. Find the area of the parallelogram

Answer 2

Answer:

12 hours & 48 minutes.

Explanation:

Step 1: find the difference between the two given Longitudes .

Step 2: multi function the difference by

4 minutes.

Step 3: If the given Longitude is to the east of Greenwich then add the calculated minutes to know the local time on that Longitude.If it is to the west dixit these minutes from the given local time,In this case 12 noon, to know the local time of that longitude.

Ex.No.1 : The longitudinal difference 0 degrees and 69 degrees East. 69 degrees. 69×4= 276 minutes .276÷ 60=4 hrs 36 minutes.

12 noon + 4 hrs 36 minutes=4 pm past 36 minutes

Ex.2 : Longitudinal difference between

0 Degrees and 30 Degrees West-30 Degrees.

30 ×4 = 120 minutes. 12 o ÷60= 2 hrs.

This being to the west dixit 2 hrs from 12 noon on Greenwich.

12- 2=10 am. It would be the local time on 30 Degrees Longitude.

Ex.3: Longitudinal difference between

0 degree and 12 Degrees East is 12 Degrees.

12×4=48 minutes.

This is to be added into 12 noon as it is to the east of Greenwich.

So on 12 Degrees East the local time would be 12 hours + 48 minutes

= 12 hours & 48 minutes.

I hope this help you out! ♡
