Question:
Solution:
The shortest distance d, from Lilly's house to the school is the hypotenuse of the right triangle in the figure. Then, we must apply the Pythagorean theorem to find this distance:
[tex]d\text{ = }\sqrt[]{(1.4)^2+(0.4)^2}[/tex]this is equivalent to:
[tex]d\text{ = }\sqrt[]{(1.4)^2+(0.4)^2}\text{ = }\sqrt[]{1.96^{}+0.16^{}}\text{ = 1.45}\approx1.5[/tex]then, the correct answer is:
[tex]1.5\text{ miles}[/tex]
