Q: Jerry drives at a constant velocity of 1 mi/min for 60 minutes. What is the total distance he covers, and which formula is used to calculate it?

60 mi, using $$d = s \times t$$

Q: Jerry accelerates his car steadily from 0 mi/min to 1 mi/min over 60 minutes. What is the area under the velocity-time graph, and what does it represent?

$$\frac{1}{2} \times 1 \text{ mi/min} \times 60 \text{ min} = 30 \text{ mi}$$, representing the total distance traveled

Q: If Jerry's velocity increases from 0 mi/min to 1 mi/min in 60 minutes, what is his acceleration?

$$a = \frac{\Delta v}{\Delta t} = \frac{1 \text{ mi/min} - 0 \text{ mi/min}}{60 \text{ min}} = 0.0167 \text{ mi/min}^2$$

Q: During the first 30 minutes, Jerry's velocity increases from 0 mi/min to 0.5 mi/min. What is the distance he covers in this interval?

$$d = \frac{1}{2} \times 0.5 \text{ mi/min} \times 30 \text{ min} = 7.5 \text{ mi}$$

Q: If Jerry slows down from 1 mi/min to 0 mi/min over 60 minutes, what is his acceleration?

$$a = \frac{0 \text{ mi/min} - 1 \text{ mi/min}}{60 \text{ min}} = -0.0167 \text{ mi/min}^2$$
