I think it would be A, because if she jogged the same amount each day she jogged then all you need to do is multiply how much she jogged by how many days she jogged.
4000. You need to round it to the nearest thousand, which would be the 4 at the start if you break it down into its units. Where from right to left, you have, 1s, 10s, 100s and 1000s. Meaning you need to keep the first digit (unless the hundreds are 500+) and everything after should just be the thousands.
Do you mean as a decimal? 11.8
