#6# km/h

Explanation:

As her jogging speed is twice her walking speed we know that 30 minutes of her jogging is equivalent to 1 hour of her walking, so add that 1 hour onto her previous 1 hour 40 minutes of walking to get 2 hours 40 minutes of walking.

Convert minutes to hours

#40/60=0.6# hours plus the other 2 hours for a total of #2.6# hours.

#16/2.6# Divide the time spent by the distance traveled to get her walking speed.
#=6.153846...#
