A train traveled 2,253 miles. Round that number to the nearest hundred.

To round 2,253 to the nearest hundred, look at the digit in the tens place, which is 5. If the tens digit is 5 or greater, you round up; if it’s less than 5, you round down.

Since the tens digit is 5, we round 2,253 up to 2,300.

So, the correct answer is 2,300.
