Mowing 3: Estimation 180 Problem

How many trips would I save using the John Deere 1445?

It is half a city block which measures 330′ x 165′.  My riding mower deck is 48″.

165′ x 12″ = 1,980″

1,980″ / 48″ = 41.25

It takes just over 41 mower decks to cut lawn.  Depending on the student, a trip will include either a full circuit or loop which will take two 48″ cuts.

So, 41.25 / 2 = 20.6

So it takes 20 full trips and a half of another to cut the lawn with the riding mower.

The John Deere 1445 cuts a mighty 120″

1,980″ / 120″ = 16.5

It would take 17 mower decks to cut the lawn.

So, 17/ 2 = 8.5 trips

Find the difference in the riding mower and the push mower.

20.5 – 8.5 = 12 trips less, you can make the movie later tonight!

(What percent decrease is this from the riding mower?  What percent decrease compared to the push mower?)
