Answer:
1.10 quarts
Step-by-step explanation:
We are given that
Capacity of system=20 quarts=
1 gallon=4 quarts
Initially mixture contains
Antifreeze=3 quarts=
Water=17 quarts=
Water runs in to the system=1gal/min
We have to find the antifreeze in the system at the end of 5 minutes.
Concentration inflow=0
Let Concentration outflow=x
Rate of system=Concentration inflow(water inflow rate)-Concentration outflow(water outflow rate)
Taking integration on both sides
Using formula
Substitute t=5
Hence, in the end of 5 minute ,the antifreeze in the system=1.10 quarts
From problem above, the pilot will make a right triangle. First find the length the missing side and then add all lengths to get total length.
Use pythagorean theorem to find the length of a.
a^2+b^2 = c^2
where
a = ?
b= 600 miles
c= 610 miles
substituting the variables, this will give us
a = 110 miles
Total length = 110+600+610
= 1320 miles
The plane flew 1320 miles.
