[Question]Kevin is taking a 600-mile trip, traveling at a rate of 50 miles per hour. How much faster must he travel to decrease his travel time by 4 hours?
[Answer]First find his current travel time 600 miles / 50 miles per hour = 12 hours. 12 hours - 4 hours = 8 hours desired travel time. 600 miles / 8 hours = 75 miles per hour. 75 miles per hour - 50 miles per hour = 25 miles per hour faster. The answer is 25.

Question: Lisa was collecting socks to donate to a homeless shelter. She bought 12 pairs at a discount store. Sandra, her friend, came over and brought her 20 pairs of socks. Her cousin showed up with one-fifth the number of pairs that Sandra bought. After work, Lisa’s mom brought 8 more than three times the number of pairs Lisa started with. How many pairs of socks did Lisa end up with?
Answer: Her cousin brought over 20 / 5 = 4 pairs of socks. Three times more than Lisa bought was 12 * 3 = 36. Her mom brought 36 + 8 = 44 pairs of socks. In total Lisa had 12 + 20 + 4 + 44 = 80 pairs of socks. The answer is 80.
[Question]Grady has 20 red numbered cubes and 15 blue numbered cubes. He gives his friend Gage 2/5 of his red numbered cubes and 1/3 of the blue numbered cubes. If Gage had 10 red numbered cubes and 12 blue numbered cubes, find the total number of cubes Gage has?
[Answer]Grady gave 2 / 5 * 20 cubes = 8 of his red numbered cubes to Gage. If Gage initially had 10 red numbered cubes, his total number of red numbered cubes became 10 cubes + 8 cubes = 18 cubes after Grady gave him 8 more. Grady also gave 1 / 3 * 15 cubes = 5 blue numbered cubes to Gage. This increased Gage's total number of blue numbered cubes to 12 cubes + 5 cubes = 17 cubes. The total number of cubes Gage has is now 17 cubes + 18 cubes = 35 cubes. The answer is 35.
Q: Emmett does 12 jumping jacks, 8 pushups, and 20 situps. What percentage of his exercises were pushups?
A: First find the total number of exercises Emmett does: 12 jumping jacks + 8 pushups + 20 situps = 40 exercises. Then divide the number of pushups by the total number of exercises and multiply by 100% to express the answer as a percentage: 8 pushups / 40 exercises * 100% = 20%. The answer is 20.
