Telling Time Formula

The Formula

\text{minutes} = \text{clock number} \times 5

When to use: A clock is like a race track with two runners—the short hand (hours) moves slowly, the long hand (minutes) moves fast. When the long hand points to 12, it's exactly on the hour, like the start of a new lap.

Quick Example

\text{Hour hand on 3, minute hand on 12} \Rightarrow 3{:}00 \text{Hour hand between 3 and 4, minute hand on 6} \Rightarrow 3{:}30

Notation

Time is written as hours:minutes (e.g., 3{:}30); each clock number represents 5 minutes for the minute hand

What This Formula Means

Reading analog and digital clocks to determine the current time in hours, half hours, quarter hours, and five-minute intervals.

Worked Examples

Example 1

easy
The minute hand points to the 3 on a clock. How many minutes past the hour is it? Remember: each number on a clock equals 5 minutes.

Solution

  1. 1
    Each number on the clock represents 5 minutes.
  2. 2
    The minute hand points to 3.
  3. 3
    Multiply: \(3 \times 5 = 15\) minutes.
  4. 4
    It is 15 minutes past the hour.

Answer

15 minutes past the hour
On a clock face, each number mark equals 5 minutes because 60 minutes ÷ 12 numbers = 5 minutes per number.

Example 2

medium
The hour hand points just past 2 and the minute hand points to 6. What time is it?

Common Mistakes

  • Reading the hour hand as pointing to the next hour when it's past the half hour
  • Forgetting that the minute hand on 6 means 30 minutes (not 6 minutes)
  • Not realizing each number on the clock face represents 5 minutes for the minute hand

Why This Formula Matters

Telling time is essential for daily life—knowing when school starts, how long until lunch, or when to go to bed.
