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)%0D%0AThe constant of proportionality is . It will take Karah how many minutes to wash 17 cars?
The constant of proportionality is 9.5.
To find the amount of time 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.
