Tia lives at the corner of 4th Street and 8th Avenue. Lei lives at the corner of 12th Street and 20th Avenue. The fruit market is [tex]\(\frac{3}{4}\)[/tex] the distance from Tia's home to Lei's home.

Where is the fruit market?

A. 6th Street and 11th Avenue
B. 10th Street and 17th Avenue
C. 9th Street and 15th Avenue
D. 8th Street and 14th Avenue



Answer :

Sure, let's break this down step by step to find the coordinates of the fruit market.

1. Identify the coordinates of Tia's and Lei's homes:
- Tia's home is at the corner of 4th Street and 8th Avenue. Hence, the coordinates are [tex]\((x_1, y_1) = (4, 8)\)[/tex].
- Lei's home is at the corner of 12th Street and 20th Avenue. Hence, the coordinates are [tex]\((x_2, y_2) = (12, 20)\)[/tex].

2. Understand the distance ratio:
- The fruit market is [tex]\(\frac{3}{4}\)[/tex] the distance from Tia's home to Lei's home. This means that the distance can be divided into 4 parts, where the fruit market is 3 parts away from Tia's home.

3. Apply the section formula to find the coordinates:
- The section formula is given by:
[tex]\[ x = \left(\frac{m}{m+n}\right) \left(x_2 - x_1\right) + x_1 \][/tex]
[tex]\[ y = \left(\frac{m}{m+n}\right) \left(y_2 - y_1\right) + y_1 \][/tex]
Where [tex]\(m = 3\)[/tex] and [tex]\(n = 1\)[/tex], since the distance ratio is [tex]\(3:1\)[/tex].

4. Calculate the x-coordinate of the fruit market:
[tex]\[ x = \left(\frac{3}{3+1}\right) (12 - 4) + 4 \][/tex]
[tex]\[ x = \left(\frac{3}{4}\right) \cdot 8 + 4 \][/tex]
[tex]\[ x = 6 + 4 \][/tex]
[tex]\[ x = 10 \][/tex]

5. Calculate the y-coordinate of the fruit market:
[tex]\[ y = \left(\frac{3}{3+1}\right) (20 - 8) + 8 \][/tex]
[tex]\[ y = \left(\frac{3}{4}\right) \cdot 12 + 8 \][/tex]
[tex]\[ y = 9 + 8 \][/tex]
[tex]\[ y = 17 \][/tex]

6. Interpret the results:
- The coordinates of the fruit market are [tex]\((10, 17)\)[/tex], meaning it is located at the corner of 10th Street and 17th Avenue.

Hence, the correct answer is:
10th Street and 17th Avenue.
