Answer:
1 1/2 kilometers
Step-by-step explanation:
She ran 1/4 of a kilometer and then ran another 10/8 kilometer.
The 5 minute rest is to throw people off, so ignore it.
10/8 can simplify to 5/4 kilometers, so you can add that to the first quarter of a kilometer she already traveled.
5/4 plus 1/4 equals 6/4.
6/4 can be simplified to 3/2 which is equal to one and one half.
1 1/2
Hope this helps!
