Which statement about the ordered pairs (2, −9) and (3, −6) is true for the equation 5x−y3=13 ? a) both ordered pairs are solutions. b) (2, −9) is a solution to the equation. c) neither ordered pair is a solution. d) (3, −6) is a solution to the equation.

the answer is b because i did this question and aced the test

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
