1. **State the problem:** We need to find how much higher Air can jump compared to Tom. 2. **Identify the given values:** - Tom's jump height: $1.62$ metres - Air's jump height: $2.1$ metres 3. **Formula used:** To find how much higher Air can jump, subtract Tom's jump height from Air's jump height: $$\text{Difference} = \text{Air's height} - \text{Tom's height}$$ 4. **Calculate the difference:** $$\text{Difference} = 2.1 - 1.62$$ 5. **Simplify the subtraction:** $$\text{Difference} = 0.48$$ 6. **Interpretation:** Air can jump $0.48$ metres higher than Tom.
