The document contains two calculus word problems and their solutions. The first problem asks at what time the temperature of a pool is highest based on a temperature model, and the answer is 4PM. The second problem asks how long the timer should be set on a camera to take a picture of someone zip lining halfway through their ride, and the answer is 44 seconds. Both problems involve taking derivatives or integrals of functions to find maximums/minimums or distances traveled over time.
