Sheila is running a 3 mile race. She runs ar a constant rate of 1/12 miles per minute. Write an equation that gives the number of miles remaining in the race, y, in terms of the numbers minutes that have elapsed since sheila started running, x

The answer to your question is y = 3 - 1/12x

Step-by-step explanation:

Data

Total distance = 3 miles

speed = 1/12 miles/min

time = it will change

Also the problem mentioned that:

distance = y and time = x

Formula

v = d/t or d = vt because we need to express the equation in terms of distance.

Also, the total distance is 3 miles so we need to consider it in the equation.

And the equation will be:

d = total distance - vt

We substitute the data given

d = 3 - 1/12t or y = 3 - 1/12x
