question:A plane flies 360 miles in 2 hours. At the same rate, how many additional hours would it take to travel an additional 240 miles?
answer:To find out how many hours it would take to travel an additional 240 miles, we need to first find out the speed of the plane.We know that the plane travels 360 miles in 2 hours, so its speed is 360 miles / 2 hours = 180 miles per hour.To travel an additional 240 miles at this speed, we can divide the distance by the speed:240 miles / 180 miles per hour = 1.33 hoursSo, it would take the plane approximately 1.33 hours to travel an additional 240 miles.Thus, the answer is boxed{1.33}.
question:Eva purchased a bike that was discounted by 30% from an original price of 180. However, she also paid an additional sales tax of 8% on the discounted price. What was the total amount Eva paid for the bike?
answer:To find the total amount Eva paid for the bike, we first calculate the discounted price and then add the sales tax.The original price of the bike is 180.Since the bike was discounted by 30%, the discount amount is 180 * 30 / 100 = 5400 / 100 = 54.The discounted price is 180 - 54 = 126.Eva also paid an 8% sales tax on the discounted price.The sales tax amount is 126 * 8 / 100 = 1008 / 100 = 10.08.So the total amount Eva paid for the bike is 126 + 10.08 = 136.08.Thus, Eva paid boxed{136.08} dollars for the bike.
question:A platinum bar is worth 100 dollars, and a copper bar is worth 10 dollars. If you have 2 platinum bars, 8 copper bars, and 50 dollars cash, how much money do you have in total?
answer:2 platinum bars are worth 2 * 100 = 200 dollars.8 copper bars are worth 8 * 10 = 80 dollars.Adding these amounts to the 50 dollars in cash gives 200 + 80 + 50 = 280 + 50 = 330 dollars.Thus, you have a total of boxed{330} dollars.
question:Samantha will have five times more tennis medals than Olivia has now in two years. If Olivia currently has 25 medals, and her collection increases by 50 medals in two years, what is the total number of medals they will have altogether after two years?
answer:Let's break it down step by step:1. Olivia currently has 25 medals.2. In two years, Olivia will have 25 + 50 = 75 medals.3. Samantha will have five times more tennis medals than Olivia has now in two years, so Samantha will have 5 * 25 = 125 medals.4. To find the total number of medals they will have altogether after two years, we add the number of medals Olivia and Samantha will have: 75 + 125 = 200.So, the total number of medals they will have altogether after two years is boxed{200}.
question:Emily wanted to purchase some scarves. She bought 3 scarves with stripes and 5 scarves with polka dots. The total cost of the scarves was 51. If the striped scarves cost 5 each, how much did she pay for each polka dot scarf?
answer:Let's denote the price of each polka dot scarf as x.The price of 3 striped scarves is 5 * 3 = 15 dollars.The total price of the scarves is 51.Since Emily bought 5 scarves with polka dots, their total cost will be 5 * x.The total cost is the sum of the cost of the striped scarves and the polka dot scarves, so we have the equation: 15 + 5*x = 51.Subtracting 15 from both sides of the equation yields 5*x = 36.Dividing both sides of the equation by 5 yields x = 36 / 5 which simplifies to x = 7.2.Thus, Emily paid boxed{7.2} dollars for each polka dot scarf.
question:Jasmine visited a toy store to buy a gift for her brother's birthday. In the store, she counted 30 scooters and 45 skateboards. How many wheels in total did the vehicles she saw have?
answer:Each scooter has 2 wheels, and there are 30 scooters, so the total number of scooter wheels is 2*30=60.Each skateboard has 4 wheels, and there are 45 skateboards, so the total number of skateboard wheels is 4*45=180.Therefore, the total number of wheels in the vehicles Jasmine saw is 60+180=boxed{240}.
