If all variables varies directly, they will be put in the numerator, and anything that varies
inversely should be written in the denominator of the right side of the equation.
a.
a varies inversely with the square root of b and directly with c.
b.
p varies jointly with the cube of q and the square of r and inversely with s.
Three men can dig 2 identical trenches in 5 hours. Assuming that all the men work at
the same rate, how long will it take for 5 men to dig 7 trenches?
2.
Note that in this situation, the number of trenches varies directly as the number
of hours and the number of men. You may use the equation z kxy, to find the value
of k. Use the value of k to answer the question.
