Question

Rowerzysta jechał z prędkością 10 m/ s . Ile kilometrów przejechał w ciągu 30 min ?

Answer 1

1min = 60sc

30min = 1800sc

1800sc x 10 = 18000m

18,000m = 18km

Przejedzie 18km

 

Answer 2

V=10m/s

t=30min

1min - 60s

30min - xs

 

x=(30min*60s):1min=1800s

 

t=30min=1800s

V=s/t /*t

Vt=s

s=10m/s*1800s=18000m

1km - 1000m

xkm - 18000m

 

x=(1km*18000m):1000m=18km

 

Odp. Rowerzysta przejechał 18km.
