Question

question 4 (4 points) (02.04 mc) a position versus time graph is shown. what is the change in position in the third hour? a 0 miles b 15 miles c 20 miles d 60 miles

Explanation:

Step1: Identify time interval

The third - hour is from \(t = 2\) hours to \(t=3\) hours.

Step2: Read positions at endpoints

At \(t = 2\) hours, the position is \(25\) miles. At \(t = 3\) hours, the position is \(25\) miles.

Step3: Calculate change in position

Change in position \(\Delta x=x_2 - x_1\), where \(x_2 = 25\) miles and \(x_1 = 25\) miles. So \(\Delta x=25 - 25=0\) miles.

Answer:

A. 0 miles
