Name the polygon below I would give more point but this is easy I woke up so I don't wanna think

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

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
