"Two buses leave Atlanta at the same time, one traveling west at 40 miles per hour and the other traveling north at 30 miles per hour. When will they be 400 miles apart?"
-----------------
Their paths form a right triangle.
At t hours after departure,
the westbound bus is 40t miles away, the northbound is 30t miles away.
----

d = 50t
----
400 = 50t
t = 8 hours
----------------
You can use the speeds in a similar manner

v = 50 mi/hr
t = 400/50 = 8 hours
