No it doesn't become positive
<span>The distance between two cities is ninety miles, and a woman drives from one city to the other at a rate of 45 mph. At what rate must she return if the total travel time is three hours and forty minutes?
1st leg DATA:
distance = 90 mi ; rate = 45 mph ; time = d/r = 2 hrs.
</span><span>2nd leg DATA:
distance = 90 mi ; time = [3 2/3 - 2] = 1 2/3 hrs; rate = 90/(5/3) = 54 mph
Ans: 54 mph</span>

The answer is E. This inequality best suits the given because in order to achieve an A she must have an average of the three test scores in which the last test score must be higher than or equal to 94. Hope this helps and have a good day!
We will use the tangent ratio since we have the adjacent side to the 65 degrees and we need to find the opposite side to the 65 degrees.
Tan α = opp/adj
Tan 65 = x/30
To solve, multiply both sides by 30.
30 Tan65 = x
x = 64 ft
