Question: The total distance between 2 towns is 200 miles. Roger and his friend drove 1/4 of the total distance, taking 1 hour to do so. They take lunch for another 1 hour and then drove the remaining distance going at the same speed as before. What's the total amount of time, in hours, Roger and his friend took to travel between the two towns?
Answer with step-by-step thinking: When they covered 1 / 4 of the total distance, they were 1 / 4 * 200 = 50 miles away from the starting point. The total distance remaining is 200 - 50 = 150 miles. If they took 1 hour to travel 50 miles, their speed was 50 / 1 = 50 miles per hour. If Roger was driving at 50 miles per hour, then the total time it took him to travel 150 miles is 150 / 50 = 3 hours. The total amount of time taken for the whole journey is 3 + 1 + 1 = 5 hours.
So the answer is 5.


Question: Students at Highridge High earn 2 points for each correct answer during a quiz bowl If a student correctly answers all the questions in a round, the student is awarded an additional 4 point bonus. They played a total of five rounds each consisting of five questions. If James only missed one question, how many points did he get?
Answer with step-by-step thinking:
If James only missed one question in all five rounds of five questions, he correctly answered 5 * 5 - 1 = 24 questions. Before the bonus, James earned 24 correct answers * 2 points / answer = 48 points. Since missing one question would only disqualify him from receiving a bonus in one round, he would earn a bonus for 5 - 1 = 4 rounds. He should expect a bonus of 4 rounds * 4 points / round = 16 points. Including his bonus, James scored a total of 48 + 16 = 64 points.
So the answer is 66.
