A.
2.9 miles


B.


29.6 miles


C.

D.
28.5 miles

Answer 1

What was the total distance Marcus biked on both days?

Answer 2

29.6 miles

Answer 3

Correct. The total distance Marcus biked was 29.6 miles. The total distance Ellen biked was the same, so it's also 29.6 miles.
Since Ellen biked 12.8 miles on Saturday, she must have biked on Thursday
29.6 miles - 12.8 miles
Just do that subtraction to find your answer.

Answer 4

The answer is not 28.5 miles

Answer 5

29.6 - 12.8 = 16.8 :D
