1 A contractor finds that Crew A takes 9- hours to construct a retaining wall and Crew B can do the same 1 job in 4- 2 wall? hours. If Crew A and Crew B work together, how long will it take them to construct the retaining a) Let h = the time to complete the job. Write the equation you would use to solve this problem. b) Now solve your equation. Give your answer first as a reduced fraction, and then a decimal rounded to 3 places. Working together, the two crews will construct the wall in hours (fraction), which as a decimal is hours.
