Which points of the following points are solutions to the equation 3x-4y-8=12? select all that apply. (0,-5) (4,-2) (8,2) (-16-17) (-1,-8) (-40,-34)

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
