A missile was fired from a submarine from 350 feet below sea level. If the missile reached a height of 10300 feet before exploding, what was the change in the altitude of the missile? Answer

To determine the change in altitude of the missile, we need to consider both the starting point (350 feet below sea level) and the highest point it reached (10,300 feet above sea level). 1. **Initial Altitude:** The missile starts **350 feet below sea level**, which can be represented as **-350 feet**. 2. **Final Altitude:** The missile reaches **10,300 feet above sea level**. **Change in Altitude** is calculated as: \[ \text{Change in Altitude} = \text{Final Altitude} - \text{Initial Altitude} \] \[ \text{Change in Altitude} = 10,300 \, \text{feet} - (-350 \, \text{feet}) = 10,300 \, \text{feet} + 350 \, \text{feet} = 10,650 \, \text{feet} \] **Therefore, the change in altitude of the missile is 10,650 feet.**
