Question

what is the lowest temperature and at what time did it occur?
a. $5^{circ}$f at 3:00 a.m.

b. $5^{circ}$f at 5:00 a.m.

c. $15^{circ}$f at 3:00 a.m.

d. $15^{circ}$f at 5:00 a.m.

Explanation:

1. Identify the lowest point on the graph, which corresponds to the minimum temperature. This point is at 4 hours on the x-axis and 15°F on the y-axis.
2. Calculate the actual time: start time is 10:00 p.m., add 4 hours. 10:00 p.m. + 4 hours = 2:00 a.m.
3. Match this result to the correct option.

Answer:

C. 15°F at 2:00 a.m.
