Question

1. what time would it be if the minute hand rotated by 180 degrees from the current time?○ 3:30○ 2:30○ 2:15○ 4:00

Explanation:

Step1: Identify current time

The clock shows the hour hand at 3, minute hand at 12, so current time is $3:00$.

Step2: Relate rotation to minutes

A full clock rotation is $360^\circ$, so $180^\circ$ is half the clock. This equals $\frac{180^\circ}{360^\circ} \times 60 = 30$ minutes.

Step3: Calculate new time

Add 30 minutes to current time: $3:00 + 0:30 = 3:30$.

Answer:

A. 3:30
