A Jet airplane leaves an airport traveling at a steady rate of 600km/h. another jet leaves the same airport 3/4h later traveling at 800km/h in the same derection. how long will the 2nd jet take to overtake the first?

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

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
