akashdeepdeb · Answer

$$Average Velocity = \frac{ v - u }{ \Delta t }$$
You have 
Δt = 5s
u = 0m/s [Starts from rest]
v = 50m/s [Convert it into SI units]

Plud the values in and you'll get the Average Velocity.

Understood? :)

Madam @pinki , 

@AkashdeepDeb gave the correct answer.

I agree with @AkashdeepDeb , also! :)

So, $v$ is the magnitude of the velocity. There is a symbol commonly used to denote the average of something. $\bar v$ is the average velocity. So, if you want to use that in your equations, or $v_\text{ave}$, you'll have formal variables!

For coding the equations,
$\bar v$ = `$\bar v$`
$v_\text{ave}$ = `$v_\text{ave}$`

Just thought I'd throw some extra information out there!
