Question

1. what time would it be if the minute hand rotated 90° clockwise from the current time? 3:55 4:25 7:10 1:10

Explanation:

Step1: Determine current minute

The current minute hand is on 2, so current minutes: \(2\times5 = 10\) (since each number represents 5 minutes). Current time is \(4:10\) (hour hand near 4).

Step2: Calculate minutes after rotation

A clock is \(360^\circ\), so each number (5 minutes) is \(360\div12 = 30^\circ\) per number. For \(90^\circ\), number of numbers: \(90\div30 = 3\). So minutes added: \(3\times5 = 15\)? Wait, no: current minute is 10 (at 2). Rotating \(90^\circ\) clockwise: each \(30^\circ\) is 5 minutes, so \(90^\circ\) is 3 intervals (each 5 min). So new minute: \(10 + 15 = 25\)? Wait, no, wait: the minute hand moves from 2. Each number is 5 minutes. \(90^\circ\) is 3 numbers (since \(3\times30^\circ=90^\circ\)). So from 2, moving 3 numbers clockwise: 2 + 3 = 5? Wait, no, 2 (10 min) + 35 min? Wait, no, \(90^\circ\) rotation: each number is \(30^\circ\), so \(90^\circ\) is 3 numbers. So minute hand moves from 2 to 2 + 3 = 5? Wait, 2 (10 min) + 35 min = 10 + 15 = 25? Wait, no, 2 (position) + 3 positions: 2 + 3 = 5, which is 25 minutes. So current time is 4:10, after rotating minute hand \(90^\circ\) (3 numbers, 15 minutes), new time is 4:25.

Answer:

4:25 (Option: 4:25)
