During a certain five-year period, the consumer price index (CPI) increased by %40,but during the next five-year period, it increased by only 20%.Which of these conditions must have existed during the second five-year period?

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

lol.

it's ok we all do this sometimes.
