Answer 1

Round each number then add

Answer 2

She estimated by rounding 245 to nearest tens and rounding 222 to nearest five.

Explanation:

Given,

The miles she drove last week = 245

Since, 245 ≈ 250 ( because the ones place digit is 5 that is we will round up )

Also, the miles she drove this week = 222,

∵ The nearest 5 of 222 is 225,

Thus, the total miles she drove = 245 + 222 ≈ 250 + 225 = 475 miles
