Answer:
The mall is <u>6 miles</u> far from there school.
Step-by-step explanation:
Given:
Marshall and Mimi walk the same distance from the school to the shopping mall. Marshall walked 2 mph while Mimi left one hour later and walked 3 mph.
If they reached the mall at the same time.
Now, to find the distance from the mall to there school.
Let the time be
As, the speed of Marshall = 2 mph.
So, the distance of Marshall =
Now, Mimi left one hour later and walked 3 mph.
Let the time of Mimi be
Speed of Mimi = 3 mph.
Thus, the distance of Mimi =
<em>As, given Marshall and Mimi walk the same distance from the school to the shopping mall and they reached the mall at the same time.</em>
According to question:
<em>Adding both sides by 3 we get:</em>
<em>Subtracting both sides by 2</em><em> we get:</em>
Now, to get the distance from the mall to there school we substitute the value of :
Therefore, the mall is 6 miles far from there school.
