Question

The hour hand is at 3. In some time it has moved to 7. How much time has passed?

• A. $7$ hours
• B. $4$ minutes
• C. $4$ hours
• D. $20$ minutes

Answer 1

The correct option is C $4$ hours

Let us consider the hands of an analog clock.

• The hour hand of the clock takes $1$ hour to move between two consecutive numbers.
• So, to move from $7$ to $3$
• Time taken $=7-3$
  $=4$ hours

Hence, the correct answer is option B.
