Just divide 10km by 3.2km to get how may hours it took.
3.125 hours or 3 hours 7 minutes and 30 seconds.

Distance = rate x time
Time = Distance / rate
Time = 10km/ 3.2 km/hr
Time = 3.125 hr
Let 's go one step further and convert to min and sec.
60 min/hr * 0.125 = 7.5 min
60 sec/min 8 0.5 = 30 sec
So it took her 3 hrs 7 min 30 sec
She must have been crawling!!
