Question: If the minute hand of a clock moves 360 degrees in 60 minutes, how many degrees does it move in 15 minutes?

Options:

Correct Answer: 90 degrees

Solution:

In 15 minutes, the minute hand moves (360 degrees / 60 minutes) * 15 minutes = 90 degrees.

If the minute hand of a clock moves 360 degrees in 60 minutes, how many degrees does it move in 15 minutes?

If the minute hand of a clock moves 360 degrees in 60 minutes, how many degrees does it move in 15 minutes?

Step 1: Understand that the minute hand of a clock makes a full circle of 360 degrees in 60 minutes.
Step 2: To find out how many degrees the minute hand moves in 1 minute, divide 360 degrees by 60 minutes. This gives you 6 degrees per minute.
Step 3: Now, to find out how many degrees the minute hand moves in 15 minutes, multiply the degrees per minute (6 degrees) by 15 minutes.
Step 4: Calculate 6 degrees * 15 minutes = 90 degrees.
Step 5: Therefore, the minute hand moves 90 degrees in 15 minutes.
