Mrs. Adam walks between 2/5 and 4/5 mile every day. Which is the best estimate of the number of miles she will walk in 30 days?

2/5 miles in one day = 2/5*30 miles in 30 days

= 60/5
= 12 miles (min)

4/5 miles in one day - 4/5*30 miles in 30 days
=120/5
=24 miles (max)

so, Mrs. Adams walks between 12 and 24 miles in 30 days.

Hope this helped!

To find the best estimate of the number of miles Mrs. Adam will walk in 30 days, we need to calculate the average distance she walks each day and then multiply it by the number of days.

Step 1: Find the average daily distance Mrs. Adam walks
The average can be found by calculating the midpoint between 2/5 and 4/5. To do this, we add the two fractions and divide the sum by 2:

(2/5 + 4/5) / 2 = (6/5) / 2 = 6/10 = 3/5

Step 2: Multiply the average daily distance by the number of days
Now we multiply the average daily distance (3/5 mile) by the number of days (30):

(3/5) * 30 = (3 * 30) / 5 = 90/5 = 18 miles

Therefore, the best estimate of the number of miles Mrs. Adam will walk in 30 days is 18 miles.
