A can paint 7 chairs in an hour.
B can paint 4 chairs in an hour.
Formula:
Total work = (A's rate)(B's rate)
Time = Total work/Combined rate
Solution:
The total work is 55 chairs. The combined rate is 7 + 4 = 11 chairs per hour. Therefore, the time required is:
Time = 55/11 = 5 hours
Therefore, A and B will require 5 hours to paint 55 chairs when they work together.
