Answer 2

If you would like to know if the trains meet the requirement, you can calculate this using the following steps:

train A: 28 cars * 40 feet = 28 * 40 = 1,120 feet > 1,100 feet
train B: 34 cars * 30 feet = 34 * 30 = 1,020 feet < 1,100 feet

The correct result would be b. Train A fails and Train B passes.
