What is Algebra?

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

A state has a limit on the lengths of cargo trains. The train cannot exceed a length of 1,100 ft.

Train A has 28 cars at 40 feet each.

Then the length of the train A will be

Length of the train A = 20 x 40

Length of the train A = 1120 feet

Train B has 34 cars at 30 feet each.

Then the length of the train B will be

Length of the train B = 34 x 30

Length of the train B = 1020 feet

The length of train A is 1120 feet and train B is 1020 feet. Then only train B meet the requirement.
