Question

Day 1: 312 miles Day 2: 490 miles Day 3: 221 miles Day 4: 270 miles Day 5: 503 miles. A group of girls are taking a road trip across the US. The distances they travel for each of the five days are shown. Which is a good estimate of the number of miles traveled over the five day period?

Answer 1

A good estimate can be determined by rounding each number of miles to the nearest hundred and then adding them.

312 - 300
490 - 500
221 - 200
270 - 300
503 - 500

A good estimate would be 1800 miles.
