Two cars travel in the same direction along a straight highway, one at a constant speed of 55 mi/h and the other at 70 mi/h.

(a) Assuming that they start at the same point, how much sooner does the faster
car arrive at a destination 10 mi away?
(b) How far must the faster car travel before it has a 15 min lead on the slower
car?


Can someone explain to me at least step by step how to solve it.. ?
