A Train left the station at 9 a.m. traveling at 50 mph, At 11 a.m., an airplane left the same place in the same direction at 175 mph. At what time did the plane overtake he train?
-------------
In 2 hours, the train is 100 miles away (d = r*t = 50*2)
The plane gains on the train at 75 mi/hr (175 - 100)
==== More precisely, the speed of the plane wrt (with respect to) the train is 75 mi/hr
-----------
t = d/r = 100/75 = 4/3 hours = 1 hr 20 mins
1100 + 1:20 = 12:20 PM
