Question

May walks a total of 3 miles to and from the library each week. She said she has walked a total of about 300 miles since she started keeping track of miles walked. Choose Yes or No to tell if the number could be the actual number of miles walked if May rounded to the nearest 10.

Answer 1

And she does this once a week, then if she started counting 50 weeks ago, then it is possible,
