A mechanic requires \(2 \mathrm{h}\) to repair a transmission, whereas an apprentice requires \(6 \mathrm{h}\) to make the same repairs. The mechanic worked alone for \(1 \mathrm{h}\) and then stopped. How long will it take the apprentice, working alone, to complete the repairs?
Simplify. $$\frac{3 x-1}{6 y^{2}}-\frac{x+5}{9 x y}$$
Simplify. $$\frac{1}{x+1}+\frac{x}{x-6}-\frac{5 x-2}{x^{2}-5 x-6}$$
To assess the damage done by a fire, a forest ranger traveled 1080 mi by jet and then an additional 180 mi by helicopter. The rate of the jet was four times the rate of the helicopter. The entire trip took \(5 \mathrm{h}\). Find the rate of the jet.
A large heating unit and a small heating unit are being used to heat the water in a pool. The large unit, working alone, requires 8 h to heat the pool. After both units have been operating for \(2 \mathrm{h}\), the large unit is turned off. The small unit requires 9 more hours to heat the pool. How long would it take the small unit, working alone, to heat the pool?
