Hey,
For this problem we need to divide 10km by 80 minutes:
10km/80min = .125 (km/min) This is the rate per minute.
Then we need to find the rate of one hour which is 60 minutes.
Therefore, we multiply this rate by 60:
.125 (km/min) x 60min = 7.5km (the minutes cancel each other out)
Therefore, she walks 7.4 km per hour
I hope this helps!
