**MathMate**, Tuesday, October 12, 2010 at 5:06pmCindy starts at 2pm, when Eric has already been cycling for two hours.

Distance apart at 2pm = 150-2*18

=114 miles

The sum of their speeds

=18+12

=30 mph

They will meet when the distance divided by the total speed equals 114 miles, or

time = 114/30 = 3.8 hours after 2 pm.

Distance travelled by each would be time * speed of each.
