This actually really frustrated me. I'm probably an 'average' math student. And this word problem is really difficult, which makes me reconsider myself even being 'average' at math.
If someone can solve this by showing there work, I'd seriously greatly appreciate it. This allows me to look at what you did and how you got your answer.
Here's the word problem.
"Batman has been thrown into an airtight cell by the Arkham Knight!
He has two tools that will cut through the six inch thick metal walls off the cell. Batman needs to cut through to reach fresh air before he suffocates.
The explosive gel blasts through the metal at a rate of 3cm/blast, But burns oxygen at a rate of 112,000 CC/Blast.
It takes 28 seconds to spray, arm and detonate an explosive gel blast.
The blowtorch cuts through the metal at a rate of 1cm/minute, but burns oxygen at a rate of 37.06 Litres/minute.
Batman takes up a space of 0.094m^3 and has reduced his breathing to consume oxygen at a rate of 5 litres/minute.
Which tool should Batman use to escape? "
