Q: Ezekiel hikes as a hobby. This past summer, he did a challenging three-day hike across 50 kilometers of wilderness. The first day, he covered 10 kilometers of steep mountainside. The second day was flatter and he was able to cover half the full hike distance. How many kilometers did he have to hike on the third day to finish the hike?
A: After the first day, Ezekiel had 50 - 10 = 40 kilometers of the hike left. On the second day, he covered 50 / 2 = 25 kilometers. Therefore, on the third day, he had 40 - 25 = 15 kilometers left to finish the hike. The answer is 15.
Question: Tobias went to a swimming pool for 3 hours. Swimming every 100 meters took him 5 minutes, but every 25 minutes he had to take a 5-minute pause. How many meters did Tobias swim during his visit to the swimming pool?
Answer: We need to count the sequences that Tobias made, which consist of 25 minutes of swimming and a 5 - minute pause, so one sequence lasts for 25 minutes + 5 minutes = 30 minutes / sequence. Three hours is 3 hours * 60 minutes / hour = 180 minutes, so he is able to make 180 minutes / 30 minutes / sequence = 6 sequences. Therefore Tobias needs to make 6 pauses within these 6 sequences, which will last for 6 pauses * 5 minutes / pause = 30 minutes. During three hours, he is going to swim for 180 minutes - 30 minutes = 150 minutes. Therefore Tobias can make 100 meters for 150 minutes / 5 minutes / 100 meters = 3 times. So he was able to swim 30 times * 100 meters / time = 3000 meters in total. The answer is 3000.
[Question]Keanu's motorcycle can store 8 liters of gasoline. If his destination is 280 miles away and his motorcycle consumes 8 liters of gasoline per 40 miles, how many times does Keanu have to refill his motorcycle with gasoline if he will make a round trip?
[Answer]The total number of miles for a round trip is 280 x 2 = 560. Therefore, he needs to refill his motorcycle 560 / 40 = 14 times. The answer is 14.
Q: Bennett sells window screens. He sold twice as many window screens in February as he sold last month. In February, Bennett sold a fourth of what he sold in March. If Bennet sold 8800 window screens in March, how many screens did Bennett sell from January to March?
A: In February, Bennett sold 8800 / 4 = 2200 window screens. In January, Bennett sold 2200 / 2 = 1100 window screens. Between January and March, Bennett sold 8800 + 2200 + 1100 = 12100 window screens. The answer is 12100.
Question: Laura's House is a 20-mile round trip from her school. The supermarket is 10 miles farther away from the school. If Laura drives to school every morning and two afternoons a week drives to the supermarket. How many miles does Laura driver per week?
Answer: 7 days a week Laura drives 20 miles to school, so Laura drives 7 x 20 = 140 miles to school in one week. The supermarket is 10 miles farther away than the school. Therefore the supermarket is 10 + 10 = 20 miles away from Laura's house. Laura drives 20 miles each way to and from the supermarket. Each trip is 20 x 2 = 40 miles. Laura drives 40 miles twice a week to visit the supermarket. Therefore she drives 40 x 2 = 80 miles in total a week to and from the supermarket. In total Laura drives 140 + 80 = 220 miles each week. The answer is 220.
Q: Lisa, Jack, and Tommy earned $60 from washing cars all week. However, half of the $60 was earned by Lisa. Tommy earned half of what Lisa earned. How much more money did Lisa earn than Tommy?
