Alice and Corine stand back to back. THey each take 10 steps in opposite directions away from each other and stop. Alice then turns around, walks toward Corine, and reaches her in 17 steps. The length of one of Alice’s steps is how many times the length of one of Corrine’s steps? Note(All of Alice’s steps are the same legnth and all Coriinne’s Steps are the same length).



The solution posted above works, but you can also “neutralize” the round-trip of Alice. She made ten steps in both directions. Had she stayed put, she would have only needed seven steps to join Corine who needed ten steps. This means you can write 10C = 7A or A = 10/7C.

Hence, the answer is 10/7. Remember to enter it as a fraction in the grid.
