Answer: 0.2m/h
Step-by-step explanation: We can say when the turtle travels 1/10 of a mile in 1/2 of an hour, he's traveled 0.1 miles in 30 minutes.
If you're looking for the turtle's rate in miles per hour, just double both the time and the distance traveled.
You will end up with 0.2 miles per hour or 2/10 of a mile per hour.
