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