Knowing the time of arrival to point X

Question

I have a bus that does A-------X------------------------B

it goes at 10 hours from A, having:

Speed at A sA = 10 m/s
constant acceleration a = -0,5 m/s2

At what hour it will be at X, knowing the distance AX dAX = 50m ?

Answer 1

Being $s = \frac{a}{2} t^2 + v t + s_0$ you might be able to work something out.
