Using SUVAT if s=(u+v)t/2
would t=2s/(u+v)?
would t=2s/(u+v)?

The discussion centers on solving for time (t) using the SUVAT equation s = (u + v)t/2. A user struggles with a specific problem involving a car accelerating uniformly from 5 m/s to 20 m/s over a distance of 500 m. They propose the rearrangement t = 2s/(u + v) and calculate t as 10 seconds, but express doubt about the accuracy of this solution. The community member encourages the user to clarify their calculations to verify the result.
PREREQUISITESStudents studying physics, particularly those learning about kinematics and uniform acceleration, as well as educators looking for examples to illustrate SUVAT applications.

I would say I am reasonably ok with it. One question I am just doubting I am right with is this:
A car accelerates uniformly from 5ms-1 to 20ms-1 over a distance of 500m.
How long does this take (t)
What is the cars acceleration? (a)
obviously using s=(u+v)t/2 but I am unsure how to rearrange it correctly. Taking a guess at 2s/(u+v)=t which provides me with an answer of 10. I don't think its correct because using t to find A i end up with 15/10 which doesn't sound correct. Please help
