The correct answer is C. One
3 5/10 - 2/5
35/10 - 2/5
35/10 - 4/10
31/10=3 1/10 or 3.1
3/5 into a percent is 60 is is less than 2/3 as a percent of 66.66
A) We can use the linear approximation to estimate the amount of time it takes. We're given that the linear approximation to t at the point x = 0 is t(x) ≈ L(x) = d(1–(x/60)). If it drives 84 miles at 62 mi/hr, we'll plug 84 in for d and 62 – 60 = 2 in for x to approximate the amount of time it takes.
L(2) = 84(1 – 2/60) = 81.2 minutes
So the answer for part a is 81.2 minutes.
b) Exact time = Distance/Speed = 84/62 = 1.35 hours, which is equivalent to 1.35 * 60 = 81.3 minutes.
