Edwin walks for 2 1/2hours. He walks 1 2/3miles in the first hour, 1 3/4miles in the second hour and 1/4 of the total distance in the last 1/2 hour. What is the total distance Edwin walks?

First arrange all of the distances as fractions

1 2/3 miles = 5/3

1 3/4 miles = 7/4

Now you have to make them common denominators

5/3 = 20/12

7/4 = 21/12

Now add them

20/12 + 21/12 = 41/12 miles

Now to find the distance in the last 1/2 hour.

41/12 x 1/4 = 41/48 miles

Now we have to add them, but first make them have common denominators.

41/12 = 164/48

Now to add it all up.

164/48 + 41/48 = 205/48 miles
