James travels 3,247 m to the park, then 582 m to the store. He then travels 1,634 m back to his house. Find the total distance traveled by first rounding each number to the nearest ten.


Rules for Rounding.

a) If the test digit is greater than or equal to 5, add 1 to the rounding digit and replace all digits to the right of the rounding digit with zeros.
b) If the test digit is less than 5, keep the rounding digit the same.

First, round each number to the nearest ten




Add the numbers:

3,250 + 580 + 1,630

= 5,460
