Homework Help: ALGEBRA

Posted by mona on Sunday, May 3, 2009 at 7:49am.

I need help with two problems to finish my assignment. #1 The length of a rectangle is fixed at 29cm. What widths will make the perimeter greater than 86 cm? If I could get the equation for this I would be able to figure it.
I saw this one posted and no response yet. #2 Trains A and B are traveling in the same direction. Train A is traveling at 100 mph and Train b is traveling at 110 mph. Train A passed a station at 1:15 pm and Train B passed the same station at 1:45pm. At what time will Train B catch up with Train A?
