A hiker 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
