Joaquin Cook · Answer 1

The train cannot exceed a length of 1100 ft. Train A has 28 cars at 40 feet each, and train B ha ... Train A = 28 * 40 Train B = 34 * 30.

Philip Oconnell · Answer 2

Train A has 28 cars at 30 ft each ... 28 * 30 = 840 ft

train B has 22 cars at 40 ft each ... 22 * 40 = 880 ft.

and both train A and B are under 1100 ft ... so both trains pass
