Side side side congruency theorem. if the three corresponding side in two triangles are congruent then the triangles are congruent
Joe completes an average of (10 ft)/(5 h) = 2 ft/hour. Bill completes an average of (10 ft)/(4 h) = 2.5 ft/hour. Together, they complete 2+2.5 = 4.5 ft/hour. At that rate, it will take them
... (120 ft)/(4.5 ft/h) = 26 2/3 h
V = 4/3 * 3.14 * 9^3 = 3052.08
