Hello there!
So, if this turtle is only going 2.5 miles per hour. This would mean that (EACH) hour, this turtle only arrived 2.5 miles. So, we do,

We would have to count how many ("2.5's" they are above.)
We count only
4.
I would take this turtle
4 miles to swim 10 kilometers.
In standard form:
answer- 14,000 and 12,000
Example
←LEFT 12,000
↑
comma(THOUSANDS PLACE)
ten thosands is the second number after the comma(thousands) to the left
The second midpoint is (-15,8)
It would be 82 2/3 since 1/3 minis 2/3 would equal -1/3 you subtract that from 83 and get 82 2/3
