Becky our tried and true lab-rat assistant came to the rescue once again. During the morning Bio-Tech class the solution of Hydrogen Peroxide was tipped over and half of the solution spilled out. The student not wanting to get into trouble filled the container with water making the solution a watered down Hydrogen Peroxide. The next class complained that the Hydrogen Peroxide solution was 50% of what it should be. Becky quickly took 1/3 of the solution out and added twice the strength of the original Hydrogen Peroxide solution. Did her idea work?
Wheres the
Fire!
A two-alarm fire alert was sent to two local fire companies to assist in a major forest fire that was raging in the far western region of the state. These two companies are right next door to each other. The first company to respond was the South Springfield Fire Company. They headed to the call at an acceptable speed. The second company from East Rockland, took an hour and a half before it sent a truck. To make up for lost time the second truck traveled at 1 1/2 times the speed of the South Springfield truck. How long will it take for the East Rockland fire truck to catch up with the South Springfield truck?
