Question

$ A truck is moving at a rate of 40 kml hr. How
for does it move when it stops after 5 seconds​

Answer 1

Answer:

450 (i think if i am right)

Step-by-step explanation:

first make the hour into second unit (3600 seconds)

now find out how much it moves in 1 second (3600/40)

now that you have that multiply it by 5(seconds)

Answer 2

Answer:

Speed = 40km/hr = 40000m/60min. =40000/3600

= 100/9m/s

So S = D/T

D = T*S

= 5*100/9

= 500/9

= 55.55m or 0.05555km (approx)

Hope you find my answer useful.

Thanks for asking.
