Last week Kate Burke ran a 5-kilometer race in 26.696 minutes. This week she ran a race in 24.003 minutes. What is the difference in Kate’s times?

To determine

**To calculate:** The difference in Kate Burke’s times when she ran a 5-kilometer race in 26.696 minutes last week and in 24.003 minutes this week.

Explanation

**Given Information:**

The provided times of race are 26.696 minutes and 24.003 minutes.

**Formula used:**

For adding and subtracting decimal numbers.

Step 1: Write all the numbers vertically aligning at decimal points.

Step 2: Add zeros to the right of the decimal numbers where ever necessary.

Step 3: Work from right to left while performing the indicated operations.

Step 4: In the answer place the decimal point is at the same place as in the problem.

**Calculation:**

To find the difference of time, subtract 24.003 from 26.696.

Now align the times vertically at decimal points,

Now perform subtraction from right to left,
