Question

Which statement about the best estimation strategy for this problem is correct? The Jackson family drove 490 miles each day for 9 days. They then flew 1,292 miles. How far did the Jackson family travel? A student answered 5,702 miles. A. 500 × 9 + 1,300 = The student's answer was reasonable. B. 500 ÷ 9 + 1,300 = The student's answer was not reasonable. C. 400 × 9 + 1,200 = The student's answer was not reasonable. D. 400 ÷ 9 + 1,200 = The student's answer was not reasonable.

Answer 1

If you would like to know which statement for this problem is correct, you can find this using the following steps:

490 miles * 9 days + 1,292 miles = 5,702 miles ... 500 miles * 9 days + 1,300 miles = 500 * 9 + 1,300 = 5,800 miles

The correct result would be: A. 500 × 9 + 1,300 = The student's answer was reasonable.
