Joseph is planting 350 acres of corn land in wheat. He is using a 30-foot rotary cutter to chop the corn stubble. He is able to drive 4,8 mph. He uses 1.2 gallons of diesel fuel per acre at a cost of $2.95 per gallon.a. Approximately how many meters wide is the rotary cutter?b. How many hours does it take to do the job?

Answer 1

(a) From the information given, Joseph is planting with a 30-foot rotary cutter.

According to the standard conversion rate,

1 foot equals 0.3048 metres

Therefore, 30 foot would be;

`\begin{gathered} 1ft=0.3048m \\ 30ft=(0.3048*30)m \\ 30ft=9.144m \\ \text{Therefore the rotary cutter is approx 9 meters wide} \end{gathered}`
