Hey I asked my dad to help me with the problem that Train A leaves New York at noon going 100 MPH, and Train B?

Jessie K asked:


leaves New York at 4 pm going 80 mph, so how long would it take train B to catch train A, and he said “Jessie, that train A has been trying to catch train B even when I was in school so if it’s still trying, it’s not going to happen.”

So does anyone out there want to hellp me for real he thinks he is funny but he’s not.

    I don’t think you understand the question. Train B is going slower that Train A, and will never catch up. Your dad is right, but not very helpful.

    if train b is going slower than train A and it leaves after it then it will not catch it in motion. The only way it will ever catch it is if the other train slows or stops.

    Well Train A wouldn’t be caught because Train B left later and is going slower.

    Maybe you got it mixed up. If Train A leaves New York at Noon going 80MPH and Train B leaves at 4PM at 100MPH.

    In four hours Train A travels 320 miles (80 * 4).

    So Train B is gaining 20 MPH each hour (100 compared to 80).

    So it’d take 16 Hours to catch the train. (16 * 20 = 320)

    i also think your dad is funny however at the same time he DID give you the answer and it was correct. i reckon this question was actually designed to see how accurately you read and thought about it without jumping in and assuming it is a maths question.
