Aline passes through (−1, 5)(−1, 5) and (1, 3)(1, 3). which answer is the equation of the line?
a. x 2y = 7
b. x 2y = 5
c. x y = 4
d. x y = 2

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
