Answer:
x = (total exercise time - walking time) / number of miles run
Explanation:
Let the time it took Maggie to run a mile = x ( already given)
x = distance ran / running speed
- Total time the whole exercise took = 125 minutes.
- Total time spent walking = 25 minutes
Total time it took her to run 9 miles can be obtained by subtracting the time she spent walking from the total exercise time.
125 - 25 = 100 minutes.
Therefore, it took Maggie 100 minutes to run 9 miles
We can set up a linear relationship as shown:
9 miles took 100 minutes
1 mile will take x minutes
x = 100 / 9 minutes.
However, the question asked us to write an equation to show this process.
We simply recap the processes in a mathematical form:
x = (total exercise time - walking time) / number of miles run
