Math Help - Math Problem

I'm having some problems with this homework question.

Two cars are travelling towards each other at 60km/h and 80km/h. How far apart are they 15 minutes before they pass each other?

Thanks.

15 min = 1/4 hr

at 60 km/hr ... one car will travel a distance of ___ in 15 min.

80 km/hr ... the other car will travel a distance of ___ in 15 min.

now, put a little thought into the question.

...or how far do you travel in 15 minutes at speed of 140 mph?
