Distance Problems

Draw a picture

#1) 2 trains depart from Pittsburgh . One train is traveling east at 40mph and one west at 30mph.
Write an equation to determine when the trains will be 245 miles apart. When will they be 245 miles apart?

Don't forget your heading.

#2) Two cylists begin traveling in the same direction on the same bike path. One travels at 20milesper hour, and the other travelign 14mph. When will the cyclists be 15 miles apart?
