Ahiker walks at a speed of 3 2 5 kilometers per hour. how many kilometers will the hiker walk in 40 minutes?

  = 2  4/15 km

Step-by-step explanation:

Speed = 3 2/5 km/hour

The units are not the same.  The speeds is in hours and the time is in minutes

Lets convert minutes to hours.  60 minutes = 1 hour

40 minutes * 1 hour/ 60 minutes = 40/60 hours = 2/3 hour

Distance = speed * time

                  = 3 2/5 * 2/3

Change the mixed number to an improper fraction

  3 2/5 = (5*3+2)/5 = 17/5

                   = 17/5 * 2/3

                  = 34/ 15  km

Change this back to a mixed number

 15 goes into 34 2 times  (15*2 = 30)  with 4 left over

                  = 2  4/15 km

so then what are you asking?
