Answer:
10 minuets
Step-by-step explanation:
an hour is 60 minuets
Julie spent 2/3 of an hour, divide 60 into 3, you get 20.
Now multiply by 2, you get 40, so 40 minuets of running.
divide 60 into 6, you get 10. Then multiply by 5 you get 50. so 50 minuets of swimming.
Now subtract 50-40, you get 10
So, Julie swam 10 minuets more than running.
