Answer:The quote”During the trip they had to fight off seven black men who tried to rob and kill them.Another quote that states this is”He subsequently worked as a hired hand, a surveyor, and a local postmaster. Tells straight off the bat how he was a self made man.
It takes them 1 7/8 hrs to complete the job together.
How:
Fred = 3 hrs
Jason = 5 hrs
1/3x + 1/5x = 1/x
3x x 5x = 15 —> 3x/15 + 5x/15 = 15/15
3x + 5x = 8x —> 8x/15 = 1.875 = 1 7/8 hrs
F(t) = 200(0.95)^t = 200(1 - 0.05)^t
<span>rate is 5% decay per unit of time.
Hopefully that is correct & I hope I helped :)</span>
