What is the expression for the velocity of the Car in Vector

[Lapse]

Homework Equations

v = I + j + k
v = d/t

The Attempt at a Solution

I thought the answer was as simple as: v = 63i + 0j + 0k, since the car only has motion in one direction...
...but I got it wrong, so clearly I'm missing something here.

The question is somewhat vague. I see two aspects that are unclear.
What units are to be used in the answer?
Does it want an expression for velocity or one for location?

I think the problem wants the expression for the position vector too, that is $\vec{r}=r_i\cdot i +0j+0k$. What is $r_i$ here?

 

[Lapse]

Whoops. Sorry, I should've had this picture there too:

 

[Delta2]

it says using the speed v and the unit vectors i,j,k

maybe try $v\cdot \vec{i} +0\cdot\vec{j}+0\cdot\vec{k}$

Thanks. I knew it was something silly.
