Common Mistakes

MISTAKE: Confusing 170 with 107 (one hundred seven). | CORRECTION: Pay close attention to the order of digits. 170 has 7 in the tens place, while 107 has 0 in the tens place and 7 in the ones place.

MISTAKE: Thinking 170 is a two-digit number. | CORRECTION: Count the digits. Since 170 has three digits (1, 7, 0), it is a three-digit number.

QUESTION: A bus travels 170 kilometers in 2 hours. If it travels the same distance in the first hour, how many kilometers did it travel in the second hour? (Hint: The question is a bit tricky!) | ANSWER: The question implies it travels 170 km in total, not 170 km in the first hour. If it travels 170 km in 2 hours, and we assume it travels half the distance in the first hour, it would be 85 km. However, the question as stated implies the total distance is 170 km. So, if it travels 'the same distance' in the first hour as the total, it's a trick question. Let's rephrase for clarity: A bus travels 170 kilometers in total. If it travels 100 kilometers in the first hour, how many kilometers does it travel in the second hour? Answer: 170 - 100 = 70 kilometers. (The original question was flawed, this is a corrected version for a good practice question).
