Answer» At 12 O'clock, A cover 40KM and on the opposite side B at 11 o clock cover 40km, again they went towards each other (which is really the separation between them), that is A needs to MAKE a trip 2HR (From 12 to 2 at 20km/hr.) i.e. 2*20=40km and opposite side B needs to Travelled out 3hr (From 11 to 2 at 40km/hr.) i.e. 3*40=120Km. At that point Then the total distance traveled by them is the Actual distance between them i.e. 40+120= 160KM At 12 O'clock, A cover 40km and on the opposite side B at 11 o clock cover 40km, again they went towards each other (which is really the separation between them), that is A needs to make a trip 2hr (From 12 to 2 at 20km/hr.) i.e. 2*20=40km and opposite side B needs to Travelled out 3hr (From 11 to 2 at 40km/hr.) i.e. 3*40=120Km. At that point Then the total distance traveled by them is the Actual distance between them i.e. 40+120= 160Km |
