Q: There is a road stretching 3 miles from the base camp to the chain challenge. Every 20 minutes, a car comes down the road from the base camp towards the chain challenge. How many hours have passed once 30 cars have come down the road?
A: 20 * 30 = 600 minutes have passed. 600 / 60 = 10 hours have passed. The answer is 10.
Question: A roll of 25 m wire weighs 5 kg. How much does a 75 m roll weigh?
Answer: We know that the 75 m roll is three times bigger than the 25 m roll because 75 m / 25 m = 3. This means the 75 m roll weighs 3 times more than the 25 m roll: 5 kg * 3 = 15 Kg. The answer is 15.
[Question]The teacher assigned a minimum of 25 pages of reading for homework. Harrison read 10 more pages than assigned. Pam read 15 more pages than Harrison and Sam read twice the amount of Pam. How many pages did Sam read?
[Answer]Harrison read 10 more than the assigned 25 pages so he read 10 + 25 = 35 pages. Pam read 15 more pages than Harrison's 35 pages so she read 15 + 35 = 50 pages. Sam read twice the amount of Pam's 50 pages so he read 2 * 50 = 100 pages. The answer is 100.
Q: There are 20 students in the orchestra and twice that number in the band. There are 12 boys and 16 girls in the choir. If each student only participates in one group, how many students, in total, are there in the orchestra, the band, and the choir?
A: There are 20 x 2 = 40 students in the band. There are 12 + 16 = 28 students in the choir. In total there are 20 + 40 + 28 = 88 students. The answer is 88.
Question: Malcolm is trying to find the fastest walk to school and is currently comparing two routes. In the first route, he walks for 6 minutes uphill, walks for twice this amount of time along a path, then finishes the journey in a third of the time it took to walk the first two stages. In the second route, he walks along a flat path for 14 minutes, then finishes the walk in twice this amount of time. In minutes, how much longer was the second route compared with the first?
Answer: In the first route, Malcolm spends 6 minutes * 2 = 12 minutes walking along the path. So in total, the first two stages of this route take him 6 + 12 = 18 minutes. This means the final part of the journey took him 18 / 3 = 6 minutes. Therefore, the total time it takes to walk the first route is 18 + 6 = 24 minutes. In the second route, the second stage takes him 14 * 2 = 28 minutes. So the second route takes a total of 28 + 14 = 42 minutes to walk. The second route therefore takes an extra 42 minutes for the second route – 24 minutes for the first route = 18 minutes. The answer is 18.
