|Two cyclists, A and B are 100 km apart travelling toward each other.|

That suggests we would look for the sum of distances traveled.


| Cyclist A has a velocity of 20 km/h south while cyclists B velocity is 15 km/h north. Find time at which each cyclist passes each other.|

They each travel the same amount of time and their distances each traveled will be different.
Let h = unknown time when distance between A and B travelers is closed.

20%2Ah%2B15%2Ah=100
35h=100
h=100%2F35=20%2F7=highlight%282%266%2F7%29 hours.
