theres one thing i don't get about this problem

"David is driving at a steady 30/s when he passes Linda, who is sitting in her car at rest. Linda then begins to accelerate at a steady 2m/s^2 at the instant David passes her"

How far does tina drive before passing him?

What is her speed as she passes him?

2. Relevant equations

a=v/t

Vf^2=vi^2 +2ad

D= Vit +1/2at^2

3. The attempt at a solution

ok so i used a=v/t to solve for the amount of time it takes to catch up to david,i used 2=30/t where t would=15 seconds

I then used that 15 seconds to calculate the distance Linda has travelled using the d=vit +1/2at^2 i got 225 from that

and then i calculated her speed by using Vf^2=Vi^2 + 2ad which equaled 30m/s

I'm just not sure about that first step when i found the time, is that part right? i'm pretty sure my last 2 steps were fine, but is that 2m/s^2=30/t right?, any help would be appreciated
