Here are two DVT quickies involving Distance, Velocity, and Time. Be careful, these are stumpers!
  1. Traffic is bad, so I only average 30 miles per hour driving to school. But I drive home at a steady 60 miles per hour. What's my average speed for the round trip?

  2. Traffic is bad again, so I drive to school at 30 miles per hour. How fast do I have to drive home to average 60 miles per hour for the round trip?
