Question 537782
A jet leaves Charlotte, North Carolina, airport traveling at an average rate of 564km/h.  Another jet leaves the airport one half hour later traveling at 744km/h in the same direction.  How long will the second jet take to overtake the first?
--------------
The 1st plane is 282 km away when the 2nd leaves (564 * 0.5)
The 2nd plane gains on the 1st at 180 km/hr (744 - 564)
282/180 = 1.56667 hours to overtake
= 1 hr 34 minutes
