Distance = rate * time
trip there, 120 = 55 *t
t = 2 and 2/11 hours
trip back, 120 = r * (2.75 - 2.181818181) round trip time - time to get there
120 = r * .568181818181818
r = 211.2 miles per hour
thinking maybe you did not copy the problem accurately...thats pretty fast.
Answer:
a
Step-by-step explanation:
As x → + ∞, y → + ∞, as x → - ∞, y → + ∞
This means as x goes to the right, y increases upwards (+ ∞) and as x increases to the left , y increases upwards (+ ∞ )
(x,y)=(x1+k(x2-x1),y1+k(y2-y1))
k is determined by writing the numerator over the sum of the numerator and the denominator of the original ratio.
k=3/(3+7)=3/10.
Point A is located at (5, 10) and point B is located at (20, 25).
(x,y)=(5+(3/10)*(20-5),10+(3/10)*(25-10))
(x,y)= (9.5,14.5)
The answer would be
(9 1/2, 14 1/2)
