Question 807277: 16. A plane leaves an airport traveling at an average speed of 340 km/h. At what distance will a 2nd plane traveling the same route at an average speed of 610 km/h catch up with the 1st plane, if it leaves 1.5 hours later? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A plane leaves an airport traveling at an average speed of 340 km/h. At what distance will a 2nd plane traveling the same route at an average speed of 610 km/h catch up with the 1st plane, if it leaves 1.5 hours later?
-----------------------
Slower plane DATA:
rate = 340 km/h ; time = t hrs ; distance = 340t km
------
Faster plane DATA:
rate = 610 km/h ; t-1.5 hrs ; distance = 610(t-1.5) = 610t-915 km
-------
Equation:
340t = 610t-915
270t = 915
t = 3.39 hrs
t-1.5 = 1.89 = 1hr 54min
