You are training twice a week for a race. On Monday, you go 4 miles in 40 minutes. Then on Wednesday you go 2 miles in 16 minutes. Write an equation where y
is the number of miles and x
is the time in minutes for the day you ran the fastest for the week.(1 point)

y=8x
y equals 8 x
y=0.1x
y equals 0.1x
y=10x
y equals 10 x
y=0.125x
y equals 0.125x
y=0.125x
To determine the number of miles (y) as a function of time (x), we need to find the running pace (miles per minute) for each day. To do this, we divide the number of miles by the time taken.
For Monday:
Pace = 4 miles / 40 minutes = 0.1 miles/minute
For Wednesday:
Pace = 2 miles / 16 minutes = 0.125 miles/minute
We are asked to find the equation where y represents the number of miles and x represents the time in minutes for the day you ran the fastest during the week. Since the pace is faster on Wednesday (0.125 miles/minute), we can write the equation as:
y = 0.125x
Therefore, the correct equation is y = 0.125x.
