[Question]Three snails raced across a rain-soaked sidewalk. The first snail raced at a speed of 2 feet per minute. The second snail raced at twice the speed of the first snail. And the third snail traveled at five times the rate of speed as the second snail. If it took the first snail 20 minutes to race all the way up the sidewalk, how long, in minutes, did it take for the third snail to race all the way up the sidewalk?
[Answer]If the first snail traveled the distance in 20 minutes, then the second snail, traveling at twice the rate of speed, would take 20 / 2 = 10 minutes to complete the race. If the third snail raced at five times the speed of the second snail, then it would take the third snail 10 / 5 = 2 minutes to race all the way up the sidewalk. The answer is 2.
Q: Granger has five times as many spots as his brother, Cisco. But Cisco has 5 less than half as many spots as his cousin, Rover. If Rover has 46 spots, how many spots do Granger and Cisco have combined?
A: If Rover has 46 spots, then half as many spots as Rover has is 46 / 2 = 23 spots. If Cisco has 5 less than half as many spots as Rover has, then Cisco has 23 - 5 = 18 spots. If Granger has five times as many spots as Cisco, then Rover has 18 * 5 = 90 spots. Thus, the total combined number of spots that Rover and Cisco have is 90 + 18 = 108 spots. The answer is 108.
Question: An amusement park sells tickets for $3. This week it welcomed 100 people per day but on Saturday it was visited by 200 people and on Sunday by 300. How much money did it make overall in a week?
Answer: During the weekdays it was visited by 100 * 5 = 500 people. On Sunday and Saturday, it was visited by 200 + 300 = 500 people. In total 500 + 500 = 1000 people visited the park in a week. So it earned 1000 * 3 = 3000 dollars in a week. The answer is 3000.
[Question]In the post-apocalyptic wasteland, 1 lizard is worth 8 bottle caps, 3 lizards are worth 5 gallons of water, and 1 horse is worth 80 gallons of water. Marla can scavenge for 20 bottle caps each day, but needs to pay 4 bottle caps per night for food and shelter. How many days does it take Marla to collect all the bottlecaps she needs to buy a horse?
[Answer]First find how many lizards you get for one gallon of water: 3 lizards / 5 gallons = .6 lizards / gallon. Then figure out how many lizards 80 gallons of water is worth: 80 gallons * .6 lizards / gallon = 48 lizards. Then figure out how many bottle caps 48 lizards is worth: 48 lizards * 8 bottle caps / lizard = 384 bottle caps. Then figure out how many bottle caps Marla can save each day by subtracting the number she spends from the number she finds: 20 bottlecaps / day - 4 bottlecaps / day = 16 bottlecaps / day. Finally, divide the number of bottle caps Marla needs by the number she saves each day: 384 bottle caps / 16 bottle caps / day = 24 days. The answer is 24.
Q: Juan bought T-shirts for his employees. He bought shirts for men and women. Women's t-shirts are $5 cheaper than men's t-shirts of the same color. His company has 2 sectors, one in white t-shirts and the other in black t-shirts. He paid $20 for white men's t-shirts and $18 for black men's t-shirts. The 2 sectors have the same number of men and women, with a total of 40 employees. How much did he spend total on buying t-shirts?
A: For each type of shirt, he needed to buy, 40 employees / 4 = 10 shirts. White men's T - shirts cost $20 / shirt * 10 shirts = $200. White women's T - shirts cost $5 less, or ($20 / shirt - $5 / shirt) * 10 shirts = $15 / shirt * 10 shirts = $150. Black men's t - shirts cost, $18 / shirt * 10 shirts = $180. Black women's T - shirts cost $ 5 less, so ($18 / shirt - $5 / shirt) * 10 shirts = $13 / shirt * 10 shirts = $130. Now add up all these quantities to find the total: $200 + $150 + $180 + $130 = $660. The answer is 660.
Question: For Roger's phone to function optimally, he can have a maximum of 50 apps on his phone. However, the recommended number of apps is 35. If Roger has twice the recommended number of apps, how many apps must he delete for his phone to function optimally again?
