A car traveling 64 miles per hour passes the bus traveling 58 in the same direction on the highway if they maintain their speed how long will it take them to be 21 miles apart
====================
The car is leaving the bus at 6 mi/hr (64-58)
----
More explicitly, the speed of the car wrt (with relation to) the bus is 6 mi/hr
-----
21/6 = 3.5 hours
============================
Is that not obvious?
