Q: Walter fell from the eighth platform of some scaffolding and fell past David after falling 4 meters. If he fell for an additional three more times that depth before hitting the ground, and the platforms are evenly spaced out in height, what platform was David on?
A: Walter fell 4 meters and an additional three times that depth which is 3 * 4 = 12 meters. He fell for a total of 4 + 12 = 16 meters. The eighth platform is 16 meters high and the platforms are evenly spaced so each platform is 16 / 8 = 2 meters high. David was located 4 meters below the 16 meter level which is 16 - 4 = 12 meters high. Each platform is 2 meters high so 12 meters would mean the 12 / 2 = 6th platform. The answer is 6.

Q: If a bunny comes out of its burrow 3 times per minute, calculate the combined number of times 20 bunnies at the same pace will have come out of their burrows in 10 hours.
A: If a bunny comes out of its hole three times in a minute, in an hour, with 60 minutes, the bunny will come out of the hole 60 * 3 = 180 times. In 10 hours, a bunny will come out of their hole 180 * 10 = 1800 times. The combined time that 20 bunnies coming out of their holes will have taken in 10 hours is 1800 * 20 = 36000 times. The answer is 36000.

Q: Trish likes to go for walks every day. One day, she goes on a 1-mile walk. Every subsequent day, she doubles the distance she walked the previous day. On what day does she walk more than 10 times further than she did on the first day?
A:
Trish walks 1 mile on the first day, and since she walks double the previous day's amount each day that means she walks 1 * 2 = 2 miles the second day. On the following day, she walks double the distance of the previous day's total of 2 miles, meaning she walks 2 * 2 = 4 miles that day. On the following day, she walks double the distance of the previous day's total of 4 miles, meaning she walks 4 * 2 = 8 miles that day. On the following day, she walks double the distance of the previous day's total of 8 miles, meaning she walks 8 * 2 = 16 miles that day. As we're looking for the first day that her distance exceeds 10 times her original total, that means we're seeking a mile total of greater than or equal to 10 * 1 = 10 miles,. Since she accomplished this on the 5th day of walking, the answer is 5. The answer is 5.
