I'm very confused...(adsbygoogle = window.adsbygoogle || []).push({});

Please help me... It seems so simple..but its just not going into my head...

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?

How to solve a problem like this? Can Someone please Help?...
