"no faster than" implies "less than or equal to"
Distance = speed * time
Let time be t, distance be d
Speed ≤ 6.3
Multiply by time both sides
Speed * time ≤ 6.3 *2
Distance ≤ 12.6 miles
Answer:
12 gallons of 20% salt solution
Step-by-step explanation:
Let
x -----> the number of gallons of 20% salt solution
we know that
20%=20/100=0.20
40%=40/100=0.40
25%=25/100=0.25
so
0.20(x)+0.40(4)=0.25(x+4)
Solve for x
0.20x+1.60=0.25x+1
0.25x-0.20x=1.60-1
0.05x=0.60
x=12 gallons
