Question

Katie set a goal to run 12 miles during the school week. She ran 3.42 miles on Monday and 2.7 miles on Tuesday. How many miles does Katie still need to run to reach her goal?
*
8.58 miles
9.3 miles
6.12 miles
5.88 miles

Answer 1

Katie ran 3.42 miles + 2.7 miles = <<3.42+2.7=6.12>>6.12 miles on Monday and Tuesday.
Therefore, Katie still needs to run 12 miles - 6.12 miles = <<12-6.12=5.88>>5.88 miles. Answer: \boxed{5.88}.
