Answer 1

Answer:

Ans. 3:20 PM

Explanation —

Earth rotates 360 ° in 24 hr.

Then in 1 hr. =360°/24=15°

1 hr.=15°

Also, 1 hr. = 60 min.

》60min.=15°

1min. = 1/4°

And, 1°= 4min.

—Earth rotates east to west . Therefore time in the east of the Prime Meridian will be ahead of that west of it and Prime Meridian itself.

50° east of it!!!

We know in 1 hr. Earth rotates 15°.

Therefore it will rotate 45° in 3hr.

Remaining 5° in 20 minutes.

HENCE, time in 50° east of it will be 3:20 PM

Keeping in mind time at Prime Meridian is 12 Noon.
