Answer:
120 miles:4 hours
Step-by-step explanation:
Johns made
<h3>two 120 mile trips</h3>
there are a total of 2 120 mile trips
<h3>his second trip in one hour less time than his first trip. The total time for the two trips was 9 hours</h3>
9 hours = 4 hours + 5 hours (5 hours - 4 hours = 1)
<h3> What was his average rate, in miles per hour, for the second trip?</h3>
120 miles:4 hours simplify to 30 miles:1 hour
The answer to this equation is 2278221
Answer is 3x(+7)= welcome
Assume that solution with 20% and 50% salt is x and y gallons respectively.
Therefore,
x+y = 300 => y=300-x
Additionally
20x+50y = 300*41 = 12300
Substituting for y
20x+50(300-x) = 12300 => 20x+15000-50x = 123000 => -30x = -2700
x= 90 gallons
y= 300-x = 300 - 90 =210 gallons
