The after 29 minutes 38 seconds, Jane and Kinsley will be 47 miles apart if they are moving in the exact opposite directions.
<h3>What is distance?</h3>
A numerical representation of the distance between two items or locations called distance. A physical length or an approximation based on other considerations in physics or common usage can be referred to as distance.
Let's suppose the at time t they are 47 miles apart.
We know, distance = speed×time
(44+51)t = 47
t = 47/95
t = 0.494 hours
t = 29 minutes 38 seconds
Thus, the after 29 minutes 38 seconds, Jane and Kinsley will be 47 miles apart if they are moving in the exact opposite directions.

Answer:
i
Step-by-step explanation:
Suppose you add x liters of pure water to the 10 L of 25% acid solution. The new solution's volume is x + 10 L. Each L of pure water contributes no acid, while the starting solution contains 2.5 L of acid. So in the new solution, you end up with a concentration of (2.5 L)/(x + 10 L), and you want this concentration to be 10%. So we have
and so you would need to add 15 L of pure water to get the desired concentration of acid.
XY=10
Y=X+3
X(X+3)=10
X^2+3X=10
X^2+3X-10
