Question

Kathleen and Arnob both run from the park entrance along a loop. Kathleen starts walking from the park entrance and gets a 5-mile head start on Arnob. The graph shows how far they have both traveled.

A coordinate grid labeled Distances Traveled with Time in minutes along the horizontal x-axis and Distance in miles along the vertical y-axis with 2 lines. The first line is labeled y equals (StartFraction 1 over 15 EndFraction) x plus 5 and passes through (0, 5) and (60, 9). The second line is labeled y equals (StartFraction 2 over 15 EndFraction) x. The lines appear to intersect at between 70 and 80 along the x-axis and 10 on the y-axis.
How many minutes does it take Arnob to catch up to Kathleen?

9.8
10
73.5
75

Answer 1

Adding the coordinate grid would be greatly appreciated, but since you are offline, I will try my best to help with the information given.

Since the graph shows how far they have both traveled, there should be two lines.

The question asks how many minutes it took for Arnob to catch up to Kathleen, so we will need to see where the two lines `intersect` so basically when Arnob and Kathleen "meet up"



This question was posted on OpenStudy a few years ago and I think the graph was also posted there, here's the link: https://questioncove.com/study#/updates/56edea04e4b07a8c8225fad7

If it is the same graph then I'd like to ask you this simple question,` where do the two lines intersect?` (Hint: I circled it in the picture attached)
