Question: Mr. Maxwell takes 1 hr to drive to work in the morning but 1 and half hours to drive back home in the evening. If the morning and evening traffic is similar and he drives at an average speed of 30mph in the morning, what is the average speed of his return journey?
Answer: In the morning he travels at an average speed of 30mph for 1 hour so he covers a distance of 30 * 1 = 30 miles. He covers the same distance of 30 miles in the evening spending 1.5 hours so his average speed must be 30 / 1.5 = 20mph. The answer is 20.
[Question]Anahi bought a 500 pages book to write some notes on. In the first week, she wrote on 150 pages. In the second week, she wrote on 30% of the remaining pages. While continuing writing, she accidentally spilled coffee on the book and damaged 20 percent of the empty pages she was to write on. Calculate the total number of empty pages available for her to write on now.
[Answer]If she bought a 500 pages book and wrote on 150 pages, the number of empty pages remaining is 500 - 150 = 350 pages. She then wrote on 30% of the remaining empty pages on the second week, a total of 30 / 100 * 350 = 105 pages. The number of remaining empty pages is 350 - 105 = 245 pages. When she spilled coffee on the remaining empty pages, the number of damaged pages was 20 / 100 * 245 = 49. The number of empty pages remaining that she could write on is 245 - 49 = 196 pages. The answer is 196.
Q: Happy Island has 60 turtles. This means there are 10 more than 2 times as many turtles on Happy Island as on Lonely Island. How many turtles are there on Lonely Island?
A: After subtracting 10 from the number of turtles on Happy Island, we get 60 - 10 = 50 turtles. Dividing this number by two, we find that the number of turtles on Lonely Island is 50 / 2 = 25 turtles. The answer is 25.
Question: On their way driving to Los Angeles, Benjamin and James see lots of billboard ads. Curious, Benjamin starts to count how many they see. In the first hour once he starts counting he counts 17 billboards. In the second hour once he starts counting he sees 20 billboards. In the third hour he sees 23 billboards. James asks Benjamin the average number of billboards they've seen per hour. What should Benjamin tell him?
Answer: Benjamin counts 17 + 20 + 23 = 60 billboards total on the way to Los Angeles. Benjamin saw those billboards over 3 hours, so the average number of billboards per hour they saw 60 / 3 = 20 billboards per hour. The answer is 20.
[Question]Mrs. Brynlee reduced the prices of items in her store by 20% after the local government gave small businesses in her county a subsidy. If the price of a shirt in the store was $60 and that of the leather jacket was $90, calculate the amount of money Teagan will pay for buying 5 shirts and 10 leather jackets at the reduced prices.
[Answer]If the price of a shirt in the store was $60, its price was reduced by 20 / 100 * $60 = $12. The price of a shirt was reduced to $60 - $12 = $48. Teagan will pay $48 * 5 = $240 for buying 5 shirts. If the initial price of the leather jacket was $90, the price reduced by 20 / 100 * $90 = $18. The final leather jacket after Mrs. Brynlee reduced the price by 20% is $90 - $18 = $72. Teagan will pay $72 * 10 = $720 for buying 10 leather jackets. The amount of money Teagan paid to Mrs. Brynlee for the shirts and the leather jackets is $720 + $240 = $960. The answer is 960.
[Question]Johan has a ten-bedroom house with 8 walls in each room. He paints 3/5 of the rooms in the house green and paints the rest of the rooms with purple color. How many walls in the house did he paint purple?
[Answer]
Since Cristian's house has ten rooms, he painted 3 / 5 * 10 = 6 rooms with green color. The number of rooms he painted with purple is 10 - 6 = 4 rooms. Since each room in the house has eight walls, the number of walls painted purple is 8 * 4 = 32. The answer is 32.
