Rounding Roads 1E6A4E

1. **State the problem:** We need to round the lengths of roads A, B, C, D, and E to the nearest 100 km and find which two roads have the same rounded length. 2. **Recall the rounding rule:** To round to the nearest 100, look at the tens digit: - If the tens digit is 5 or more, round up. - If the tens digit is less than 5, round down. 3. **Round each road length:** - Road A: 208 km - Tens digit is 0 (less than 5), so round down to $$200$$ km. - Road B: 364 km - Tens digit is 6 (5 or more), so round up to $$400$$ km. - Road C: 126 km - Tens digit is 2 (less than 5), so round down to $$100$$ km. - Road D: 313 km - Tens digit is 1 (less than 5), so round down to $$300$$ km. - Road E: 193 km - Tens digit is 9 (5 or more), so round up to $$200$$ km. 4. **Compare rounded lengths:** - Road A rounds to $$200$$ km. - Road E rounds to $$200$$ km. 5. **Conclusion:** Roads A and E have the same length when rounded to the nearest 100 km, which is $$200$$ km.
