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.
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
