conversations.value: This math problem has got me stumped: Kim drives 30 miles to her friend's house.  On the way back she has to take a detour that is 20% longer.  She spends 30 minutes at her friend's house.  She drives at a speed of 44 mph.  How long did she spend away from home?
  Can you show me the way?

conversations.value: The trip back was 30*.2=6 miles longer than the trip there.
  So it was 30+6=36 miles.
  So the total drive was 30+36=66 miles.
  That means she drove for 66/44=1.5 hours.
  She stayed with her friend 30/60=.5 hours.
  So the total time was 1.5+.5=2 hours.
