[Question]Jill can run up a hill at 9 feet/second and down a hill at 12 feet/second. How long does it take her to run up and down a 900 foot hill?
[Answer]First find the time it takes Jill to run up the hill: 900 feet / 9 feet / second = 100 seconds. Then find the time it takes Jill to run down the hill: 900 feet / 12 feet / second = 75 seconds. Then add the two times to find Jill's total time: 100 seconds + 75 seconds = 175 seconds. The answer is 175.

[Question]Fiona and Casey share the hoodies they own. Between the two of them, they own eight hoodies. Casey owns two more than Fiona. How many hoodies does Fiona own?
[Answer]Let H be the number of hoodies Fiona owns. Casey owns H + 2 hoodies. Together, they own H + H + 2 = 2H + 2 = 8 hoodies. Thus, 2H = 8 - 2 = 6 hoodies. Therefore, Fiona owns H = 6 / 2 = 3 hoodies. The answer is 3.

[Question]A retailer sells any shirt for the same price and any pair of pants for the same price, but the price of shirts and pants are not the same. Say you bought 2 shirts and 3 pairs of pants for $120 in total, then you realized you didn't need the extra pants. What's the price of 1 shirt at this place if when you returned all 3 pairs of pants you were refunded 25% of what you originally paid?
[Answer]If I paid $120 and I was refunded 25% for all the 3 pants, then that means I received 25% * 120 = $30. This means the total price of the 2 shirts was 120 - 30 = 90. The price of one shirt is thus 90 / 2 = 45. The answer is 45.

First convert the total length of the journey from kilometers to meters: 9 kilometers * 1000 meters / kilometer = 9000 meters. Then divide this by the length of one step to find the number of steps in the journey: 9000 meters / 3 meters / step = 3000 steps. Then multiply the number of steps by the number of flowers per step to find how many flowers one unicorn creates on the journey: 3000 steps * 4 flowers / step = 12000 flowers. Then multiply the number of flowers per unicorn by the number of unicorns to find the total number of flowers created: 12000 flowers / unicorn * 6 unicorns = 72,000 flowers. The answer is 72000.
