Answer:
y= 120+20x
y=30x
When jamie and owen walk for same minutes then: 120+20x=30x
Step-by-step explanation:
Given :
Jamie has already walked 120 minutes and plans to walk 20 minutes per day. Owen plans to walk 30 minutes per day.
To Find: . 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
Solution :
Let x represent the number of days and y represent the total number of minutes walked during the challenge.
Since Jamie plans to walk 20 minutes per day
So, Jamie walked for x days =20 x minutes
Jamie already walked for 120 minutes
So total minutes for which jamie walked :
y= 120+20x ---(a)
Since Owen plans to walk 30 minutes per day
Owen walk for minutes in x days = 30x
So, y=30x ---(b)
Now when jamie and owen walk for same minutes then:
120+20x=30x
⇒120=10x
⇒x=12
Thus jamie walked for minutes = 120 +20*12 =360
Own walked for minutes = 30*12 =360
