The correct answer is:
15≤s≤22.5
(15 less-than-or-equal-to s less-than-or-equal-to 22.5)
Based on the graph, it can be observed that Kaitlyn reaches 1.25 miles between the time interval of 15 minutes and 22.5 minutes.
Use the image to answer the question.
A piecewise linear function consisting of five parts is plotted in quadrant 1 of a coordinate plane.
On Friday, Kaitlyn went to the park to work out. She started with a slow jog at a constant rate for five minutes. She then increased her speed to a faster, constant pace for seven minutes. She took a three-minute break, then ran for another 7.5 minutes at a constant pace to finish her two-mile run. She rested for the remainder of the time. During what domain interval will she reach 1.25 miles?
