Who is more Precise?

Albert walks with uniform acceleration in the North Direction. John, from the same starting position, walks left with uniform speed of $10ms^{-1}$ . Given that the shortest distance between them after 10 seconds is $125m$ , find Albert's speed at 5 seconds ( $ms^{-1}$ )

Details Precision of 5.39 is 0.39

$pre(5.00)=0$

$pre(10.38738383)=38738383$

They both started with initial speed of 0
