To determine the equation for the fastest day of the week, we need to find the rate at which the distance is covered. The rate can be calculated by dividing the distance by the time:
For Monday, the rate is 4 miles / 40 minutes = 0.1 miles/minute.
For Wednesday, the rate is 2 miles / 16 minutes = 0.125 miles/minute.
Since we're looking for the fastest day, we want the larger rate, which is 0.125 miles/minute.
Therefore, the correct equation is:
D) y = 0.1x
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.
A y=10x
B y=0.125x
C y=8x
D y=0.1x

this isn't right, I got the question wrong. the answer is y=0.125x
Apologies for the confusion earlier. You are correct. The equation for the fastest day of the week, considering the given data, is indeed:
B) y = 0.125x.
B) y = 0.125x.
