Question

Jon currently skates three miles a day, two days a week at a skating rink. How can he increase the intensity of his skating?

1.Start skating five days a week
2.Start skating in hilly areas
3.Switch to skating four miles each day
4.Add 10 minutes to each skating session

Answer 1

Answer: b

hope this helps

Answer 2

I would go with B(Start Skating In Hilly Areas).
If you think through the other options, A, C, and D don't really add up.
Option A would change the frequency.
Option C would change the distance.
Option D would change the duration.
So that leaves Option B which would make skating more difficult, hence increasing the intensity.
Hope this helps :-)
