Calculating Flee's Acceleration After Take-Off

[N2]

Hello,
A flee jumps a horizontal distance of 0.035m with an angle of 70°.
I calculated the startspeed, v0, to 0.73m/s (projectile motion) - but then I am asked the following:
"What is the flee's average acceleration, if the startspeed is achieved after a take-off on 8.0 * 10^(-4) m"
How should i interpret the this situation?( As the startspeed being zero, and the flee accelerating to point where the speed, v0, is achieved? sounds odd to me)

If you assume a constant acceleration, a (the average acceleration), then the final speed is at= 0.73m/s and the distance is (1/2)at²= 8.0 x10^-4m. Solve those two equations to find a.
