conversations.value: Roberto is out for a hike. He travels uphill at 2 MPH and downhill at 3MPH. The trail is 5 miles long. 60% is uphill and the rest is downhill. How long does it take him to complete it in minutes?

conversations.value: There is 3 miles uphill because 5 x .6 = 3
  This takes him 1.5 hours because 3 / 2 = 1.5
  This takes him 90 minutes because 1.5 x 60 = 90
  40% of the trail is downhill because 100 - 60 = 40
  There are 2 miles of downhill because 5 x .4 = 2
  This takes him 2/3 of an hour because 2 / 3 = (2/3)
  This takes him 40 minutes because 60 x (2/3) = 40
  It takes him 130 minutes in total because 90 + 40 = 130
