Answer 2

Solution :-

we know that,

• Greenwich is located at 0° longitude .
• One degree of longitude takes 4 minutes time .
• In east longitude time increases .

So,

→ Time at greenwich = 12 noon .

→ Place situated at = 60° east longitude .

then,

→ 1° east longitude = 4 minutes ahead

→ 60° east longitude = 4 × 60 = 240 minutes ahead .

now,

→ 60 minutes = 1 hour

→ 1 minute = (1/60) hour

→ 240 minutes = (1/60) × 240 = 4 hours .

therefore,

→ Required time at given place = 12 noon + 4 hours = 4 PM (D) (Ans.)
