Question

Which number sentence below matches this word problem? Grandma's house is 7 miles away. Aunt Millie's house is only 5 miles away. How much farther is Grandma's house than Aunt Millie's? A. 5 + 7 = 12 B. 7 × 5 = 35 C. 7 - 2 = 5 D. 7 - 5 = 2

Answer 1

D. 2

Explanation:

• If the houses are in the same pathway, the exercise says that starting from the place we are, Grandma's house is 7 miles away (we have to drive 7 miles to get there), while Aunt Millie's house is 5 miles away (we only have to drive 5 miles away to get there).
• Then, if we drive 5 miles to Aunt Millies's house first, we should only have to drive two more miles to reach Grandma's house. Then, the houses are two miles separeted by two miles.
