Answer: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 milesDistance covered on Monday= 2. 7 milesDistance covered by Lisa on Wednesday = 3.65 milesLet 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 milesor, 6. 35 miles + k miles = 10 miles⇒ k = (10 - 6. 35) miles = 3.65 miles or, k = 3.65 milesHence, Lisa needs to run 3.65 miles on Friday to complete a 10 miles marathon.
