The question: If a plane travels 1400 miles in 1 hour, how many miles does it travel in 3 hours?
The student's answer: 1 million?
AAAAAAHHHHHH!!!!! Tell me there is a sure-fire trick for explaining this to him.
Do you laugh, cry, scream or jump up and down? Depending on the student, I'd say there is probably no guarantee, but I'd probably use a map and clock drawings. Use a scaled line
Lol I have one better?
"Looking at the graph, what color shirt is the class's favorite?"--six

It sounds like something visual might help. Obviously just hearing it or reading it isn't working. See what happens with the manipulatives and a visual approach. Best wishes!
