The equations for the distance travlled by the two planes are
X1 = 600 (t + 0.75) and
X2 = 800 t
where t is the time after the second plane leaves.

Set X1 = X2 to find the time t when Jet 2 overtakes Jet 1

800 t = 600 t + 450
200 t = 450
t = ? hours

i don't really get what you just said

What part don't you understand?
X1 is the distance travelled by the first car to leave. X2 is the distance travlled by the second car to leave.

I left you the last step to solve.

t = 450/200 = 2.25 hours is the answer
