Constant Acceleration ProblemFinding time given total distance and two accelerations?

    1. The problem statement, all variables and given/known data

    A crate is initially at rest on a rough, horizontal floor. The crate moves in a straight line as it is pushed resulting in the crate speeding up at a constant rate of 2.85 m/s2. After a while, the crate is no longer being pushed and the crate slows down at a constant rate of 4.17 m/s2. The crate comes to rest a total distance 92.7 m away from its starting position. For how long (amount of time) was the crate pushed?
    Round to 3 sig figs

    2. Relevant equations



    3. The attempt at a solution

    You forgot part 2 (relevant equations) and 3 (your attempt at a solution).
    You can get help here, but not complete solutions.
