Question

Wpisz drogę, prędkość lub czas:

1.V=20km/h, s=?, t=2,5h

2.V=450km/h, s-?, t=20min

3.V=?, s=15km, t=0,5h

4.V=?, s=240km, t=45min

5.V=40km/h, s=180km, t=?

6.V=240km/h, s=4km, t=?

DAM NAJ!

Answer 1

1. s= v*t = 20km/h*2,5h= 50km

2. s=240km/h*1/3h= 80km

3. v=s/t = 15km/ 0,5h = 90km/h

4. v=240km/ 3/4h = 320km/h

5. t=s/v = 180km/ 40km/h= 4.5h

6. t= 4km / 240km/h = ok. 0.02h

Answer 2

s=v*t

1.V=20km/h, s=?, t=2,5h ..... s = 50km

2.V=450km/h, s-?, t=20min ...... s=150km

v=s/t

3.V=?, s=15km, t=0,5h ..... v= 30km/h

4.V=?, s=240km, t=45min  ..... v=320km/h

t=s/v

5.V=40km/h, s=180km, t=? ...... t=4,5h

6.V=240km/h, s=4km, t=? ...... t ≈ 0.0166666 ≈ 0.017h
