10. Robin and Batman meet at the subway. Robin walks \( 6 / 6 \) of a mile to the subway. Batman flies \( 10 / 11 \) of a mile to the subway. Who traveled a greater distance? Explain.

To compare the distances Robin and Batman traveled, let's simplify the fractions. Robin walked \( 6/6 \) of a mile, which equals 1 mile since \( 6/6 = 1 \). On the other hand, Batman flew \( 10/11 \) of a mile. Now, comparing 1 mile to \( 10/11 \) of a mile, we can see that 1 mile is greater than \( 10/11 \) (because if you think about it, \( 10/11 \) is just slightly less than a full mile). Hence, Robin traveled a greater distance than Batman. So, the answer is Robin! He walked an entire mile, while Batman just flew a little under a mile.
