Multiplying by 4 using the doubles strategy utilizes the fact that 4 is double of 2. Hence, 4 time any number is double of 2 times that number.
Thus, given 4 x 8, it can be evaluated using the double strategy as follows 2 x 8 + 2 x 8 = 16 + 16 = 32.
Well, you get 2n miles for each of the first 3 days and n miles for each of the other 4. That is, 2n+2n+2n+n+n+n+n=56.5. That is, 10n=56.5 or n=5.65 miles each of the last 4 days. The first 3 days, Luke jogged double that, that is, 11.3 miles each day.
Answer:
27.5 miles.
Step-by-step explanation:
44km ÷ 8km = 5.5
5.5 x 5 = 27.5
