Set up two equations:
1st: P (for Price family) + J (for Jenkins family) = 45 hours
2nd: 20P + 35J = 1200 liters
Rewrite the first equation as P = 45 – J
Replace P in the second equation:
20(45-J) + 35J = 1200
Simplify:
900 -20J + 35J = 1200
900 +15J = 1200
Subtract 900 from both sides:
15J = 300
Divide both sides by 15:
J = 300/15
J = 20
Jenkins used theirs for 20 hours
Price used theirs for 45-20 = 25 hours.
The answer would be the last choice
The formula for finding time is the distance divided by the velocity.So the answer is 100÷30=3.3333...
6/40 is equalvilant because all you have to do is double or simplify it by 2
The Width Should Be 130 Because If You Subtract 182-52 You Get 130
