Karah can wash 2 cars every 19 minutes. This relationship is represented by the equation y=9.5x, where x is the number of cars and y is the number of minutes. Identify the constant of proportionality. How long will it take Karah to wash 17 cars?(1 point) The constant of proportionality is . It will take Karah minutes to wash 17 cars.
The constant of proportionality in the equation y=9.5x is 9.5.
To find out how long it will take Karah to wash 17 cars, we can substitute x=17 into the equation:
y=9.5x
y=9.5(17)
y=161.5
Therefore, it will take Karah 161.5 minutes to wash 17 cars.
