Kim ran 3 one-mile races, 6 two-mile races, 4 five-mile races, and 1 ten-mile race. what is the mean number of miles kim ran in the races? show your work! (hint: find the total length of all races and the total number of races.)

To find means number, you need to find the sum of all number and divided it for 14 in this case.
We know that:
Kim ran 3 one-mile races, which is 3 miles total
Kim ran 6 two-mile races, which is 6×2=12 miles total
Kim ran 4 five-mile races, which is 4×5=20 miles total
Kim ran 1 ten-mile race, which is 10 miles total, which means that Kim ran total:
3+12+20+10=45 miles, then the means will be:
45/14≈3.21. As a result, the means is about 3.21. Hope it help!
