Q: Greg's PPO algorithm obtained 90% of the possible reward on the CoinRun environment. CoinRun's maximum reward is half as much as the maximum ProcGen reward of 240. How much reward did Greg's PPO algorithm get?
A: Half of much as ProcGen's maximum reward is 240 / 2 = 120 reward. 90% of CoinRun's maximum reward is 120 * .9 = 108 reward. The answer is 108.
Question: Camp Cedar has 40 boys, it has 3 times as many girls. It needs 1 counselor for every 8 children. How many counselors does Camp Cedar need?
Answer: Camp has 3 * 40 boys = 120 girls. Camp Cedar has a total of 40 boys + 120 girls = 160 children. Camp needs 1 counselor per 8 children, so 160 children / 8 children = 20 counselors needed. The answer is 20.
[Question]If we assume all thirty 4-wheel drive cars in the parking lot have their spare tire with them, how many tires are in the parking lot?
[Answer]Each car has 4 tires + 1 spare = 5 tires. If there are 30 cars in the parking lot and each one has 5 tires, then the total number of tires is 30 * 5 = 150 tires. The answer is 150.
Q: Danny helps his friends carpool to work. He has to drive 8 miles to the first friend's house, half that distance to the second friend's house, then 3 times the total distance driven so far to get to work. How many miles does Danny drive between the second friend's house and work?
A: First find the distance to the second friend's house by halving the distance to the first friend's house: 8 miles / 2 = 4 miles. Then add that amount to the distance to the first friend's house: 4 miles + 8 miles = 12 miles. Then triple that number to find the distance from the second friend's house to work: 12 miles * 3 = 36 miles. The answer is 36.
Question: Janet starts driving across a lake in a speedboat going 30 miles per hour. Her sister follows in a sailboat that has a speed of 12 miles per hour. If the lake is 60 miles wide, how long does Janet have to wait on the other side for her sister to catch up?
Answer: First find how long it takes Janet to cross the lake: 60 miles / 30 miles / hour = 2 hours. Then find how long it takes her sister to cross the lake: 60 miles / 12 miles / hour = 5 hours. Then subtract Janet's travel time from her sister's travel time to find the difference: 5 hours - 2 hours = 3 hours. The answer is 3.
Q: For her gift present, Lisa has saved $1200. She asks her mother, as well as her brother, to help her raise the total amount of money she needs to buy the gift.,If her mother gave her 3/5 times of what she had saved and her brother gave her twice the amount her mother gave her, calculate the price of the gift she wanted to buy if she still had $400 less.
A:
Lisa's mother gave her 3 / 5 * $1200 = $720 for her birthday gift. She also received 2 * $720 = $1440 from her brother for the gift. If she still had to find $400 to fully reach her birthday gift cost, it means her gift's total cost was $1200 + $1440 + $720 + $400 = $3760. The answer is 3760.
