## At what time do the hands of a clock make a straight line vertically across a dial?

Explanation: The hands of a clock point in opposite directions (in the same straight line) **11 times in every 12 hours**. (Because between 5 and 7 they point in opposite directions at 6 o’clcok only). So, in a day, the hands point in the opposite directions 22 times.

## How many times do clock hands Cross in 12 hours?

The key insight: In order to get back to being lined up at noon, the hands must pass each other **11 times every 12 hours**. That means, if you divide 12/11, you should get the length of each interval between crossings.

## How many times clock hands coincide in a day?

Also, the hour and minute hand coincide only once between 11 and 1 o’clock i.e. at 12 o’clock. So, from both the above statements we can say that the two hands coincide exactly 11 times in a 12 hour span. times. So, the number of times the two hands coincide in a day is **22 times**.

## What is the time between 2 and 3 o clock?

The hour hand and minute hand of a clock together means the angle between angle and minute hand will be 0°. Hence, ‘ **10 10 11 min**. past 2 is the correct answer.

## At what time between 1 and 2 o’clock will the hands of a watch makes an angle of 180?

## How many times does a clock have 90 degrees?

If you switch to a rotating coordinate system in which the hour hand stands still, then the minute hand makes only 11 revolutions, and so it is at right angles with the hour hand **22 times**. In a 24 hour day you get 2×22=44.

## How many times from 4pm to 10pm the hands are at right angles?

Every hour the hands of a clock are at right angles twice i.e. in 6 hours (4 to 10) they would be right angles to each other **12 times**.
