Lisa is training for a marathon. she needs to run 10 miles by the end of the week. she ran 2.7 miles on monday and 3.65 miles on wednesday. how many more miles does she need to run on friday?

Lisa needs to run 3.65  miles on Friday to complete a 10 miles marathon.

Step-by-step explanation:

Total distance to be run in the marathon in a week =  10 miles

Distance covered on Monday= 2. 7 miles

Distance  covered by Lisa on Wednesday = 3.65 miles

Let us assume Lisa  runs k miles on Friday to complete the marathon.

The, according to the question:

Distance covered on (Monday + Wednesday + Friday) = Total Distance

⇒ 2. 7 miles + 3.65 miles + k miles = 10 miles

or, 6. 35 miles + k miles = 10 miles

⇒  k  = (10 -   6. 35)  miles  = 3.65 miles

or, k = 3.65 miles

Hence,  Lisa needs to run 3.65  miles on Friday to complete a 10 miles marathon.
