A jet leaves the Charlotte, North Carolina, airport traveling at an average rate of 564 km/h. Another jet leaves the airport one half hour later traveling at 744km/h in the same direction. Use an equation to find how long the second jet will take to overtake the first.

Answer 1

Use the fact that at the moment of "overtaking" they would have gone the same distance

Time for slower plane --- t hrs
time for faster plane ---- t-1 hrs

564t = 744(t-1)

continue, solve for t ,

Answer 2

that was a half hour later.
