Question

The earth rotates 360° about its axis in
about 24 hours. By how much degree
will it rotate in 7 hours 30 minutes​

Answer 1

Answer:

112.5°

Step-by-step explanation:

7 hours and 30 minutes = 7.5 hours

24 hours → 360°

1 hour → 360 ÷ 24

⇒ 1 hour → 15°

7.5 hours → 15 × 7.5

⇒ 7.5 hours → 112.5°

∴ In 7 hours and 30 minutes, the Earth rotates by an angle of 112.5°
