Question
At what time, in minutes, between 3 o'clock and 4 o'clock, both the needles will coincide each other?
- A) 1341113411''
- B) 1641116411''
- C) 51115111''
- D) 1241112411''
Solution
The question is asking for the time between 3 o'clock and 4 o'clock when the minute and hour hands of a clock will overlap or coincide.
Here's how to solve it:
-
At 3 o'clock, the minute hand is at 12 and the hour hand is at 3.
-
The minute hand moves 12 times faster than the hour hand.
-
So, the minute hand will catch up to the hour hand at some point between 3 o'clock and 4 o'clock.
-
To find out when, we can set up an equation. Let's say that "m" is the number of minutes past 3 o'clock when the hands coincide.
-
In "m" minutes, the minute hand will move 12m degrees (since it moves at a rate of 12 degrees per minute).
-
The hour hand moves at a rate of 0.5 degrees per minute, so in "m" minutes it will move 0.5m degrees.
-
Since the hour hand starts out 90 degrees ahead of the minute hand (since it's at 3 and the minute hand is at 12), we can set up the following equation to find out when the minute hand will catch up:
12m = 0.5m + 90
- Solving for "m" gives us m = 16.36 minutes.
So, the minute and hour hands will coincide approximately 16 minutes and 22 seconds past 3 o'clock.
Therefore, the correct answer is B1641116411''.
