The world high jump record for men is 2.45 m.The world high jump record for women is 2.09 m.Express the difference in millimetres.

1. ### Break Down the Problem

To find the difference between the men's and women's high jump records, we will follow these steps:

1. Convert both heights from meters to millimeters.
2. Calculate the difference between the two heights in millimeters.

2. ### Relevant Concepts

1 meter is equivalent to 1000 millimeters. Thus, we can express heights in millimeters using the formula: $\text{Height in mm} = \text{Height in m} \times 1000$

3. ### Analysis and Detail

• Men’s record: $2.45 \text{ m} = 2.45 \times 1000 = 2450 \text{ mm}$

• Women’s record: $2.09 \text{ m} = 2.09 \times 1000 = 2090 \text{ mm}$

Now, calculate the difference: $\text{Difference} = 2450 \text{ mm} - 2090 \text{ mm} = 360 \text{ mm}$

4. ### Verify and Summarize

Both heights have been converted correctly from meters to millimeters. The difference has been calculated accurately.

Final Answer

The difference between the world high jump records for men and women is $360 \, \text{mm}$.
