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?

Answer 1

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.
