Answer:
I dont understand the question much but let's see if what I think is right is right. Christen is winning bc he has a mixed number, so he had the fraction and a whole number, which is more than the rest of them. I dont understand the what is the runner winning now, but maybe it means how much more does he have to run until 2 miles. I got 1 7/8
Step-by-step explanation:
if christen ran 1 1/8, subtract 2 miles from the 1 mile he ran, (the first 1 in 1 1/8) so that gives you 1 mile left to run. if he already ran 1 1/8, add 7 to the 1/8 to make it 8/8, or 1. 1+1=2.
2-1=1. 1/8+7/8=8/8=1. 1+1=2 miles. idk if this is right or not.
