Remark
Start by figuring this out for 1 car. Worry about the 7 part when you find 1.
This problem is used quite frequently in physics. For example resistors in parallel use the same equation.
Formula
1/frank + 1/carla + 1/missy = 1/ time taken to do 1 mar.
Givens
Frank = 2 hours
Carla = 2 hours
Missy = 3 hours.
Substitute and Solve
1/2 + 1/2 + 1/3 = 1/Three_together.
3/6 + 3/6 + 2/6 = 1/Three_together.
8/6 = 1/Three_together. Cross multiply
8 * Three_Together = 6*1
8 * Three_Together = 6 Divide by 8
Three_Together = 6/8 = 3/4 = 0.75 hours. or 45 minutes for 1 car
Seven Cars
For 7 cars multiply 0.75 by 7
7 * 0.75 = 5.25 hours. <<<< Answer
For part A, The answer is that the car gets better gas mileage. We can see it from the graph that the number of gallons used is on the X axis, and the distance traveled using those number of gallons is on the Y axis. The easiest way to compare would be to look at the 1 gallon of gas. You can see that you can travel 25 miles on 1 gallon of gas. The truck on the other hand will get you 18 miles per gallon. Imagine putting 1 in for X, the Y value would be 18 if you did this. The graph just shows us a visual way of saying the same thing. To determine how much farther the car with a girl on 8 gallons of gas, you would just multiply 8 by 25 for the number of miles traveled by the car. You would multiply 8 by 18 to find the number of miles traveled for the truck. The answers are 200 miles for the car and 144 miles for the truck. 200-144=56 miles farther for the car.
Ggggggggg you want me to do that for one thing and she will it your you will your life mother of I
