[Question]A forester is planting trees. The forest already has 30 native trees. On Monday he triples the number of total trees in the forest by planting new trees. On Tuesday, he plants a third of the amount he planted on Monday. How many trees has the forester planted in total?
[Answer]Let M be the number of trees he plants on Monday. On Monday the forest was three times larger from the trees that were originally there and the M trees: 3 * 30 = 30 + M trees. So, 90 = 30 + M. And, M = 60 trees. On Tuesday, he planted 60 trees / 3 = 20 trees. In total, he has planted 60 trees + 20 trees = 80 trees. The answer is 80.
Q: Marta works on her grandparent's farm to raise money for a new phone. So far, she has collected $240. For every hour she works, she receives $10. Her grandmother often gives her tips, and she has collected $50 in tips in total. How many hours has Marta worked on the farm so far?
A: Ignoring tips, Marta earned $240 - $50 = $190. Therefore, she has worked 190 / 10 = 19 hours. The answer is 19.
Question: Apple can run at a rate of 3 miles per hour. Mac can run at a rate of 4 miles per hour. In minutes, how much faster will Mac run a 24 mile race?
Answer: First find how fast each runs. Apple = 24 miles / 3 miles per hour = 8 hours. Mac = 24 miles / 4 miles per hour = 6 hours. Mac runs 8 hours - 6 hours = 2 hours faster. 1 hour = 60 minutes, so, Mac runs faster by 2 hours * 60 minutes = 120 minutes. The answer is 120.
[Question]To get to work, Ryan bikes one day a week takes the bus three times a week and gets a ride from a friend once a week. It takes him thirty minutes to bike to work. The bus takes ten minutes longer since it stops at every bus stop for other passengers. His friend driving him is the fastest and cuts two-thirds off his biking time. How many minutes does he spend every week commuting to work?
[Answer]The bus to Ryan's work takes 10 minutes longer than his bike ride, so it takes 10 + 30 = 40 minutes. Ryan takes the bus 3 times a week, so the bus rides take 40 * 3 = 120 minutes a week. His friend cuts two - thirds off his biking time, which is 2 / 3 * 30 = 20 minutes a week. This means his friend takes 30 - 20 = 10 minutes to drive him. Therefore, Ryan spends 120 + 10 + 30 = 160 minutes every week commuting to work. The answer is 160.
[Question]Bob can shuck 10 oysters in 5 minutes. How many oysters can he shuck in 2 hours?
[Answer]
He shucks 10 oysters in 5 minutes we need to know how many 5 minute units are in 60 minutes so 60 / 5 = 12 units. He can shuck 10 oysters in 5 minutes and there are 12 5 minute units in an hour so he can shuck 10 * 12 = 120 oysters in 1 hour. If he can shuck 120 oysters in 1 hour, so for 2 hours in can shuck 2 * 120 = 240 oysters. The answer is 240.
