Mowing Madness

Matt, a boy in our neighborhood, run a mowing business in the summer.

When Matt complained to his father that he was bored while mowing, his father quickly replied, "How about exercising your brain while you work on the lawns?I imagine there are many ways to look at mowing the lawns mathematically."

Since Matt loves a math challenge, he decided to give this a try.For one week, he decided he would cut all lawns by starting at the outside part of the lawn and mowing a path completely around the outside edge.Then, he would mow a second path around the remaining portion of the lawn, and he would continue "Matt-Mowing" until he competed the entire lawn.

While he mowed, Matt would create additional challenges for himself by

calculating the dimensions of the rectangles he was mowing, as well as predicting the dimension of the last rectangle he would mow to complete the job.

Matt's lawn mower cuts a path 2 ft. wide. pullWhat else do you need to know?

Question:

Find the dimensions of the last "Matt-mowed" rectangle that would fit in a 48 ft. by 64 ft. yard.

Jasmine likes to play kickball at lunch recess.Patrick prefers handball.

To do this, she first needs to go to the gym and check out a ball before she heads out to the playground.

The length of the line varies when she gets there, so some days it takes longer to check out the ball than others. The end of the, which was pretty typical, it took the following amounts of time for Jasmine to get from the cafeteria out to the playground:

·Wednesday - 2 minutes and 8 seconds·Thursday - 3 minutes and 14 seconds·Friday - 2 minuters and 43 seconds

He has his own handball which he carries in his pocketso he goes directly to the playground after they've beendismissed from the cafeteria.

Question?

1. On average, how long does it take Jasmine to get the ball and get out to the playground?

2. About how much more recess time does Patrick have each week, since he goes straight to the playground with his handball?
