Cara can wash two cars every 19 minutes this relationship is represented by the equation Y equals 9.5X where X is the number of cars and Y is the number of minutes. identify the concept of proportionality how long will it take Cara to wash 17 cars
The constant proportionality is ____. It will take her ____ minutes to wash 17 cars.
The constant proportionality in this situation is 9.5, as it is multiplied by the number of cars (X) to give the number of minutes (Y).
To find out how long it will take Cara to wash 17 cars, we can substitute X = 17 into the equation and solve for Y:
Y = 9.5 * 17
Y = 161.5
Therefore, it will take Cara 161.5 minutes to wash 17 cars.
The constant proportionality is 9.5. It will take her 161.5 minutes to wash 17 cars.
The concept of proportionality in this scenario is represented by the equation Y = 9.5X, where Y is the number of minutes it takes Cara to wash X number of cars. The constant of proportionality in this equation is 9.5, which means that for every car washed, it takes 9.5 minutes.
To find out how long it will take Cara to wash 17 cars, we can use the equation Y = 9.5X and substitute X with 17:
Y = 9.5 * 17
Y = 161.5
Therefore, it will take Cara approximately 161.5 minutes to wash 17 cars.
