Explanation / Answer

As we know that we have
x(t)=x0+v0 t + 1/2 at^2

x(t)=position as a function of time
x0=initial position
v0=initial speed (which here is zero for both horses)
a=acceleration
t=time

for George, we have:

x(t)=0+0+1/2 (0.389)t^2

for Arthur, we have:

x(t)=90.8+0-1/2(0.204)t^2 (accel is negative since it is in the opposite direction of George's

they meet when the have the same value of x:

0.1945t^2=90.8-0.102t^2

0.2965t^2=90.8 or t=17.49969887 s

plug this into the george equation to get:

x(t=17.4996s)=0.1945(17.4996)^2=59.56357504 m
