Question

Use the image to answer the question 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? (1 point) Responses 22.5≤s≤25 22.5≤s≤25 15≤s≤22.5 15≤s≤22.5 5≤s<12 5≤s<12 12≤s≤15

Answer 1

Based on the given information, Kaitlyn started with a slow jog for 5 minutes and then increased her speed for 7 minutes. This means that in the first 12 minutes, she has covered a distance less than 1.25 miles.

After the 12 minutes, she took a 3-minute break, so the total time elapsed becomes 12 + 3 = 15 minutes.

Then, Kaitlyn ran for another 7.5 minutes to finish her two-mile run. This means she covered 2-1.25=0.75 miles during this time.

Therefore, Kaitlyn would have covered a distance of 1.25 miles after 15 + 7.5 = 22.5 minutes.

So, the domain interval when she will reach 1.25 miles is 15 ≤ s ≤ 22.5.
