Remember our Eqn---->-->
We're looking for the highlighted one above.
.
After 2 hours as the Jet leaves the airport, we want to know at what distance is the airplane now:

Then the Jet flies when the airplane is at 384 km away.
At this time, because they're flying on the same direction.
*But to remember to add 384km to the plane.
So,

, OR 30 minutes
AT this time, both airplane and jet will be on the same DISTANCE.
Check,

Therefore, after 0.50hr, the jet will overtake the plane.
Thank you,
Jojo
