Answer:
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.
Hope it helps you!!!!!
