Step-by-step reasoning process: One hour contains 60 minutes so 2 hours contain 60 * 2 = 120 minutes. Alpha Epsilon's running time is 30 minutes less than that of Millennium (which runs for 120 minutes) hence 120 - 30 = 90 minutes. Beast of War: Armoured Command runs for 10 minutes more than Alpha Epsilon hence 90 + 10 = 100 minutes.
[Q & A] The question is The running time of Beast of War: Armoured Command is 10 minutes longer than that of Alpha Epsilon, which is 30 minutes shorter than that of Millennium. If Millennium runs for 2 hours, what is the running time of Beast of War: Armoured Command in minutes?
The answer is 100

Step-by-step reasoning process: Maurice buys 4 * 5 = 20 pounds of ground beef. If 2 pounds of ground beef make a burger, then he can make 20 / 2 = 10 burgers. Given that Maurice will have 1 burger, he can invite 10 - 1 = 9 people.
[Q & A] The question is Since it is Maurice's turn to host this year's neighborhood cookout, he goes to the local wholesale club to buy ground beef. The wholesale club sells ground beef in 5-pound packages. Maurice wants to make one 2-pound burger for each person that attends, so he purchases 4 packages of ground beef. How many people can Maurice invite to the cookout so that everybody, including himself, gets a burger?
The answer is 9

Step-by-step reasoning process: In 7 years, Kaylee will be 5 * 3 = 15 years old. Let x be the age Kaylee is now. After 7 years, Kaylle will be 15 years old, so x + 7 = 15. x = 15 - 7. x = 8 years old.
[Q & A] The question is In 7 years, Kaylee will be 3 times as old as Matt is now. If Matt is currently 5 years old, how old is Kaylee now?
The answer is 8

Step-by-step reasoning process: If Kelly weighs 15% less than Megan, this means Kelly's weight is 100 - 15 = 85% of Megan's weight. 85% is 0.85, so Megan weighs 34 / 0.85 = 40 kilograms. Mike weighs 5 kilograms more than Megan, so he weighs 40 + 5 = 45 kilograms. In total all three kids weigh 34 + 40 + 45 = 119 kilograms. That means to cross the bridge safely, they weigh 119 - 100 = 19 kilograms too much.
[Q & A]
The question is A small, old, wooden bridge can hold up to 100 kilograms at once. Mike, Megan, and Kelly are three children who decided to cross the bridge at the same time. Kelly weighs 34 kilograms, which is 15% less than Megan. Mike weighs 5 kilograms more than Megan. How much too much do the three children weigh together to cross the bridge?
The answer is 19
