Question

Jamie and Owen joined a monthly walking challenge at their youth center. Jamie has already walked 120 minutes and plans to walk 20 minutes per day. Owen plans to walk 30 minutes per day. Let x represent the number of days and y represent the total number of minutes walked during the challenge. Which system of equations can be used to find the number of days it will take for Owen and Jamie to have walked the same number of minutes?

A) y= 20x + 120
y=30

B) y=20x
y=30x + 120

C) 120x + 20
y=30

D) y=120x
y=30x +20

Answer 1

I think the best answer would be letter B. Y= 20x and Y= 30x+120. So by calculating it through substitution you will come up to 20x = 30x+120. By simplifying the equation it will give you an answer of 12 days. 

Answer 2

Answer:

Actually the answer would be A)y= 20x + 120

y=30

Step-by-step explanation:

Jamie already walked 120 minutes and he wants to walk for 20 minutes each day so you would put y=20x+120 as your equation

For Owen he wants to walk for 30 minutes each so it would be y=30x

P.S You forgot to put the x after Owens equation
