By what I can tell, that is telling you what the measurement of rain was per month. For example, August had 10. That means that in the month of August there was 10 inches of rain.
3 miles X 4 times a week is =12 miles a week so 12 miles X 6 =72 miles
The answer is 37/50......
Well, you first have to convert the 85 mm to cm, which you divide it by 100, and you get 8.5 cm, then add that with itself and you get 17 cm.
