1 answer

To estimate the number of miles that Rose hiked during that time, we can round the rate of 13.3 miles per day to the nearest whole number, which is 13 miles per day.

Multiplying this rate by the number of days (7), we get:
13 miles/day * 7 days = 91 miles

Therefore, Rose hiked approximately 91 miles during that time.

The answer is A. 91 mi.
