Figure abcdef was reflected across the line y = –x to create figure a'b'c'd'e'f'. what are the coordinates of the pre-image of f'? (–2, 4) (4, 2) (2, –4) (–4, –2)

the barter

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
