With modern farming equipment, wheat can be harvested at a rate of 2 acres per hour (exact numbers). If a farmer harvests wheat for 4.30 hours, how many square miles of field will be cleared? Notes: 1 mile (exact) = 5280 feet; 1 acre (exact) = 43,560 square feet Set up the problem using dimensional analysis. Show all your work in the attached supplement. Then type your final answer in scientific notation in the box below. Answers in scientific notation should be written using the caret to stand for the exponential. For example, 3 x 105 is 3*10^5. Note that you do not need to include units in the box. But watch your sig figs!

Question
Transcribed Image Text:With modern farming equipment, wheat can be harvested at a rate of 2 acres per hour (exact numbers). If a farmer harvests wheat for 4.30 hours,
how many square miles of field will be cleared?
Notes: 1 mile (exact) = 5280 feet; 1 acre (exact) = 43,560 square feet
Set up the problem using dimensional analysis. Show all your work in the attached supplement. Then type your final answer in scientific notation in
the box below. Answers in scientific notation should be written using the caret to stand for the exponential. For example, 3 x 105 is 3*10^5. Note
that you do not need to include units in the box. But watch your sig figs!
Expert Solution
Step 1: Unit conversion
To solve this problem we have to change the unit the given area.
Given that
1 miles = 5280 feet
1 square miles = 5280 × 5280 square feet
1 acre = 43560 square feet
