Astate has a limit on the length of cargo trains the train cannot exceed a length of 1100 feet train a has 28 cars at 30 feet each and trays be has 22 cars at 40 feet each do the trains meet the requirement

the train cannot exceed a length of 1100 feet

Now, train A = 28 cars at 30 feet each 

Therefore, Train A's total length = 28*30 = 840 feet < 1100 feet.

Now, train B = 22 cars at 40 feet each 

Therefore, Train B's total length = 22*40 = 880 feet < 1100 feet.

Thus, both the trains meet the requirement.
