Do you know if these two formulas are the same?
Avg. Velocity = Distance Traveled / Time Traveled
&
Avg. Velocity = V1 + V2 / 2 (V1 = d1/t1 & V2 = d2/t2)
I have a problem that says that a plain goes from a place to another(1) and from there it goes to another place (2).
So:
t1 = 3 h & d1 = 375 km
t2 = 2 h & d2 = 250 km
and using both of the formulas I get the same Average Velocity.
So:
Formula 1 = (375/3 + 250/2)/2 = 125 m/s
.......... ----> Formula 1 = Formula 2
Formula 2 = (375 + 250)/(3+2) = 125 m/s
So I'm guessing they are the same. But my science teacher says they're not.
Do you agree with my teacher? How come?
If you think its right, can you show me a mathematical way to prove it?
Thanks.
P.S. Please answer ASAP.
