club can clean up trash on a 2-mile (d)
stretch of road in 1 hour (t).
a. Write a mathematical sentence that relates
the quantities? (2 points)
b. What is the constant of variation? (2 points)
c. Express the s in terms of d and t. (2 points)
d. How long it will take to clean the same stretch
of road if only 5 students show up to help?
(4 points)
Hint: y varies directly as x and inversely as z if there
is some positive constant k such that: y =
kx
Z

Answer:

[tex]a. \: s = k \frac{d}{t} [/tex]

[tex]b. \: s = k \frac{d}{t} \\ 10 = k \times \frac{2}{1} \\ 10 = 2k \\ 5 = k \\ k = 5[/tex]

[tex]c. \: s = 5 \frac{d}{t} [/tex]

[tex]d. \: s = 5 \frac{d}{t} \\ 5 = 5 \times \frac{2}{t} \\ 5 = \frac{10}{t} \\ t = \frac{10}{5} \\ t = 2[/tex]

therefore, t = 2 hours
