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? 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.
