Prove, by mathematical induction, that f 0 + f 1 + f 2 + ⋯ + f n = f n + 2 − 1 , f0+f1+f2+⋯+fn=fn+2−1, where f n fn is the n nth fibonacci number ( f 0 = 0 , f0=0, f 1 = 1 f1=1 and f n = f n − 1 + f n − 2 fn=fn−1+fn−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
