Stephan can run 3 miles in 15.75 minutes. Kelsha can run 5 miles in 226 minutes. Who can run faster?
Unit rate for Stephan:
Unite rate for Kelsha.

Step-by-step explanation:

Stephan can run

3 miles in 15.75 minutes

1 miles in 15.75/3 minutes

1 miles in 5.25 minutes

Kelsha can run

5 miles in 226 minutes

1 miles in 226/5 minutes

1 miles in 45.2 minutes

Stephan can run faster, since 5.25 < 45.2

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
