**SOLVED**

## Homework Statement

You and a friend each drive 50 km. You travel at 90km/h; your friend travels at 95km/h. How long will your friend wait for you at the end of the trip?

D

_{f}(Displacement Final): 50km

D

_{i}(Displacement Initial): 0

V

_{me}(My Avg Velocity): 90km/h

V

_{friend}(etc.): 95km/h

T=???

## Homework Equations

I don't know! It's like I know I should know them but I can't seem to find anything in the chapter -_-

## The Attempt at a Solution

I attempted first to break this down(since all the equations I know use seconds and meters) via dimensional analysis and this is how it turned out(note: I rounded one of the numbers)

Code:

```
90km 1h 90km 1m 90km ended up w/ 0.025km/s
----- x ----- = ---- x ---- = ----- for the friend I got 0.026km/s
1h 60m 60m 60s 3600s
```

90km=0.000025m 95km=0.000026m

But I don't really know what to do from here; I mean I know that I need to make those conversions but from here I don't know what formula to use!

Were my conversions wrong? Unnecessary?

What formula do I need! Someone help, I have a quiz on this stuff tomorrow -_-

Thanks in advance!
