If one plane is flying at 40 mph while another is flying at 100 mph, and they are 200 miles apart and flying directly towards each other, how long will it take them to meet?
-----------------------
1st Plane DATA:
rate = 40 mph; time = t hrs ; distance = 40t miles
-------------
2nd Plane DATA:
rate = 100 mph ; time = t hrs ; distance = 100t miles
---------------------------
Equation:
dist + dist = 200 miles
40t + 100t = 200 miles
140t = 200 miles
t = 1.429 hrs = 1hr 25.7 min = 1hr 25min 43sec
