Question

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

Answer 1

Answer:

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
