Explanation:

Step1: Analyze the graph's y - axis (speed)

The y - axis of the graph represents speed in miles per hour. We need to find the highest and lowest values on the y - axis that the graph reaches.
Looking at the graph, the initial speed is 40 mph (at time 0 minutes), then it changes. The highest point on the graph (maximum speed) and the lowest point (minimum speed) need to be identified. From the given numbers (25, 40, 50, 65, 70) and the graph, we can see that the maximum speed reached is 65 mph (by looking at the peak of the graph) and the minimum speed is 25 mph? Wait, no, wait. Wait, the initial speed is 40, then it goes down? Wait, no, let's re - examine. Wait, the graph: at time 0, speed is 40. Then it decreases? Wait, no, the y - axis is speed (miles per hour) from 0 to 70. Wait, the graph's first segment is from (0,40) then it goes down? Wait, no, maybe I misread. Wait, the options are 25, 40, 50, 65, 70. Wait, the maximum speed: looking at the graph, the highest point (the peak) is at 65? Wait, no, maybe the maximum is 65 and minimum is 25? Wait, no, let's think again. Wait, the problem is about the graph of driving speed over time. The y - axis is speed. So to find maximum speed, we look for the highest y - value on the graph, and minimum speed is the lowest y - value. From the given numbers, 25, 40, 50, 65, 70. Let's assume that the graph's minimum speed is 25 and maximum is 65? Wait, no, wait, maybe I made a mistake. Wait, the first blank is maximum speed. Let's check the graph again. Wait, the graph: at time 0, speed is 40. Then it goes down? No, maybe the graph has a peak at 65 and a low at 25. Wait, the numbers provided are 25, 40, 50, 65, 70. So for maximum speed, the highest among these that the graph reaches is 65, and minimum is 25? Wait, no, wait, maybe the maximum is 65 and minimum is 25? Wait, no, let's correct. Wait, the initial speed is 40. Then the graph goes down to 25? No, maybe the minimum speed is 25 and maximum is 65. Wait, the problem says "Ms. Collin's maximum speed was _ miles per hour. Ms. Collin's minimum speed was _ miles per hour." From the given numbers, the maximum should be 65 and minimum 25? Wait, no, wait, maybe I messed up. Wait, let's look at the graph again. The y - axis is speed (0 - 70). The graph: at time 0, speed is 40. Then it decreases? No, maybe it increases? Wait, the x - axis is time (minutes) from 0 to 10. The first point is (0,40). Then the next points: as time increases, speed changes. The peak (maximum) and the trough (minimum). Among the numbers 25, 40, 50, 65, 70, the maximum speed is 65 (the highest value the graph reaches) and the minimum speed is 25 (the lowest value the graph reaches). Wait, but 40 is the initial speed. So maximum speed: 65, minimum speed: 25? Wait, no, maybe I am wrong. Wait, let's check the numbers. The options are 25, 40, 50, 65, 70. So for maximum speed, the highest is 65, and minimum is 25. So:

Step1: Find Maximum Speed

Look at the graph's y - values (speed). The highest y - value (maximum speed) among the given options that the graph reaches is 65 miles per hour.

Step2: Find Minimum Speed

The lowest y - value (minimum speed) among the given options that the graph reaches is 25 miles per hour.

Answer:

Maximum speed: 65, Minimum speed: 25
