Darryl left the White House and traveled toward the ferry office at an average speed of 25 mph. Some time later Jacob left trave
DanielleElmas [232]

Answer:

2 hours

Step-by-step explanation:

Given the following :

Darryl :

Speed = 25mph

Jacob:

Traveled in opposite direction

Speed = 35mph

After Darryl had traveled for 4 hours, Distance between them was 170 miles

Distance traveled by Darryl :

Speed * time = (25 * 4) = 100 miles

Total distance = distance traveled by Darryl + distance traveled by Jacob

170 miles = 100 miles + distance traveled by jacob

Distance traveled by Jacob = 170 - 100

Distance traveled by Jacob = 70 miles

Time = distance / speed

Time traveled by Jacob = 70 miles / 35mph

Time traveled by Jacob = 2 hours

One canned juice drink is 25% orange juice; another is 10% orange juice. How many liters of each should be mixed together in ord
Vikki [24]
Let's say we use "x" of the 25% OJ... ok... well, how much juice is really in that "x" liters?  well, 25% of it is OJ, the rest is water, how much is 25% of x? well, (25/100) * x,  or 0.25x.

likewise, we'll use "y" of the 10% OJ, and it will end up with (10/100) *y or 0.10y of juice in it.

whatever "x" and "y" are, they must add up to 15 Liters, and the juice concentration on that mixture, must also be the sum of their sum concentration.

\bf \begin{array}{lccclll}&#10;&\stackrel{liters}{amount}&\stackrel{juice~\%}{quantity}&\stackrel{juice}{quantity}\\&#10;&------&------&------\\&#10;\textit{25\% juice}&x&0.25&0.25x\\&#10;\textit{10\% juice}&y&0.10&0.10y\\&#10;------&------&------&------\\&#10;mixture&15&0.17&2.55&#10;\end{array}&#10;\\\\\\&#10;\begin{cases}&#10;x+y=15\implies \boxed{y}=15-x\\&#10;0.25x+0.10y=2.55\\&#10;----------\\&#10;0.25x+0.10\left(\boxed{15-x}  \right)=2.55&#10;\end{cases}&#10;\\\\\\&#10;0.25x-0.10x+1.5=2.55\implies 0.15x=1.05\implies x=\cfrac{1.05}{0.15}&#10;\\\\\\&#10;x=7

how much will be it of the 10% juice?  well, y = 15 - x.
