Answer:
16.7 miles per hour.
Step-by-step explanation:
1/10 hour is equal to 6 minutes so it takes him 6 minutes to walk 1/6 mile. So he's walked 1 mile in 36 minutes.
Then we divide 1 mile by the time it took him to walk it to know how much distance he walks in 1 minute 1 mile/36=0.277777778
Then you multiply this by 60 because an hour has 60 minutes
0.277777778 x 60=16.7
This means he is walking at 16.7 mph
