The total distance, in miles, that kara walked at the park this week is 57/20.

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that kara walks five days each week. this week she walked 7/8 mile on monday, 3/5 mile on tuesday, 4/10 on wednesday, 1/10 mile on thursday, and 9/10 mile on friday.

Now, in order to find the total distance, in miles, that kara walked at the park this week.

kara walked on Monday = 7/8

kara walked on Tuesday = 3/5

kara walked on wednesday = 4/10

kara walked on thursday=1/10

kara walked on friday= 9/10

Now, to get the total distance in miles by adding both the miles she walked this week:

7/8 + 3/5 +4/10 + 1/10 + 9/10

35/40 + 24 / 40 + 14/10

59/40 + 14/10

114/40

57/20
