Question
You want to develop a formula for estimating how long it takes to mow a lawn for your lawn-mowing personal business. The lawn mower cuts a swath that is 18in wide. One turn is required at the end of each swath. On average, 600ft^2 of lawn clippings fill one bushel. The time elements required for each activity are given in the table below. Construct a formula to estimate time for cutting rectangular lawns of various dimensions. Compute the time needed to cut a lawn that is 75ft by 100ft. Is it more economical to cut swaths in the long dimension or short dimension? Why? What can you suggest to minimize the time required?Explanation / Answer
b.
total perimeter of rectangle = 2(75+100)=350ft
area of rectangle=75*100=7500
no of bushel required=7500/600
rectangle has 4 corners
total time taken:
7.5+3.5+.005*350+.20*4+.010*7500+3*75/6+6=88.55 min
