Step-by-step reasoning process: If Danielle drives at three times the speed of Cameron, it will take Cameron 30 * 3 = 90 minutes for Cameron to travel the same distance. And since Cameron drives at twice the speed of his brother, Chase, it will take Chase 90 * 2 = 180 minutes to travel from Granville to Salisbury.
The question and answer:
Question and answer: Cameron drives at twice the speed of his brother, Chase. But Danielle drives at three times the speed of Cameron. If it takes Danielle 30 minutes to travel from Granville to Salisbury, how long, in minutes, will it take Chase to travel from Granville to Salisbury?
The answer is 180

Step-by-step reasoning process: First find the number of stairs the players climb up and down each time: 32 stairs * 2 = 64 stairs. Then multiply the number of stairs per run by the number of runs to find the total number of stairs the players climb: 64 stairs / run * 40 runs = 2560 stairs. Then multiply the number of stairs by the number of calories each stair burns: 2560 stairs * 2 calories / stair = 5120 calories.

Question and answer: The football coach makes his players run up and down the bleachers 40 times. Each time they run up and down 32 stairs one way. If each stair burns 2 calories, how many calories does each player burn during this exercise?
The answer is 5120

Step-by-step reasoning process: She loses 5 marbles because 25 x .2 = 5. She has 20 marbles after this because 25 - 5 = 20. Her friend gives her 40 marbles because 20 x 2 = 40. Adding those marbles to the 20 she had before, she ends up with 40 marbles + 20 marbles = 60 marbles.
