<u>Answer:</u>
The older repear will harvest in 6 hrs
<u>Explanation:</u>
Given a field can be harvested in 1 hr with 2 reapers
Consider the total field to be 1
Let x be the time of older’s reaper
The field can be harvested in 1.2 hr with newer reaper alone
Older’s time of harvesting = 
per hour
Newer’s time of harvesting = 
per hour
Total (Older+Newer) = 1 = 
}
1.2 + x = 1.2x
1.2 = 0.2x
x = 6
Therefore, older repear will harvest in 6 hrs

It is somewhat problematic for Bob to see the top of a white pine tree at that angle of elevation. His view would likely be obscured by the branches of the tree.
The answer is A, first the question said parallel so it should have same gradient and the gradient of the equation is 2 So eliminate D and bring (3,1) in each of the last three equation, and you will find just A conformed
