Taa lives at the corner of 4th Street and 8th Avenue. Les's fruit market is [tex]\(\frac{1}{4}\)[/tex] the distance from Taa's home to Les's home.

Where is the fruit market?

A. 8th Street and 11th Avenue
B. 10th Street and 17th Avenue
C. 9th Street and 15th Avenue
D. 8th Street and 14th Avenue



Answer :

To determine the location of the fruit market given that it is [tex]\(\frac{1}{4}\)[/tex] the distance from Taa's home to Lei's home, we will use the concept of the section formula. This formula helps find a point that divides a line segment between two points in a given ratio. Here’s the step-by-step solution:

1. Identify the coordinates of Taa’s and Lei’s homes:
- Taa’s home: [tex]\((x1, y1) = (4, 2)\)[/tex]
- Lei’s home: [tex]\((x2, y2) = (8, 8)\)[/tex]

2. Determine the ratio [tex]\( m:n \)[/tex]:
- The fruit market is [tex]\( \frac{1}{4} \)[/tex] of the distance from Taa's home to Lei's home, which can be expressed as [tex]\(1:3\)[/tex] in terms of section formula ratio, since [tex]\(1 + 3 = 4\)[/tex].

3. Apply the section formula to find the coordinates:
- The section formula for a point [tex]\(P(x, y)\)[/tex] dividing the line segment joining [tex]\((x1, y1)\)[/tex] and [tex]\((x2, y2)\)[/tex] in the ratio [tex]\(m:n\)[/tex] is:
[tex]\[ x = \frac{{m x2 + n x1}}{{m + n}} \][/tex]
[tex]\[ y = \frac{{m y2 + n y1}}{{m + n}} \][/tex]

4. Substitute the values into the formula:
- For [tex]\(x\)[/tex]-coordinate:
[tex]\[ x = \frac{{1 \cdot 8 + 3 \cdot 4}}{{1 + 3}} = \frac{{8 + 12}}{{4}} = \frac{20}{4} = 5 \][/tex]
- For [tex]\(y\)[/tex]-coordinate:
[tex]\[ y = \frac{{1 \cdot 8 + 3 \cdot 2}}{{1 + 3}} = \frac{{8 + 6}}{{4}} = \frac{14}{4} = 3.5 \][/tex]

5. Determine the nearest street and avenue:
- The [tex]\(x\)[/tex]-coordinate for the fruit market is 5, which corresponds to 5th Street.
- The [tex]\(y\)[/tex]-coordinate for the fruit market is 3.5, which we round to the nearest whole number, resulting in 4, corresponding to 4th Avenue.

Conclusion:

The fruit market is located at 5th Street and 4th Avenue.
