“Stop! Mr. R.,” screamed Justin, “Don’t vaporize the school!”
“Go ahead, vaporize it!” grumbled Greg who was beginning to wake-up.
“Don’t Mr. R., please, anything but vaporizing the school!” yelled David, “I love this place like a brother.”
“The school’s your brother?” asked Serena,”You must have some strange looking parents!”

According to Mr. R. how many minutes would it be until the school started vaporizing?
