We have a question: Kwame studied for the history test for 2.5 hours. Connor studied for 1.5 hours and Lexia studied for 97 minutes. How many minutes more did Kwame and Connor study than Lexia?
And an answer: 143
So how you got the answer?
Kwame = 2.5 hours * 60 minutes = 150 minutes. Connor = 1.5 hours * 60 minutes = 90 minutes. Kwame + Connor = 150 + 90 = 240 minutes. 240 - 97 = 143 minutes. Kwame and Conner studied 143 minutes more than Lexia.

We have a question: Thomas is 6 years old. His older sister, Shay, is 13 years older than him and 5 years younger than their older brother, James. How old will James be by the time Thomas reaches his current age?
And an answer: 42
So how you got the answer?
Shay is 6 + 13 = 19 years old. James is 19 + 5 = 24 years old. Thomas will be 24 in 24 - 6 = 18 years. James will be 24 + 18 = 42 years old.

We have a question: A store sells 20 packets of 100 grams of sugar every week. How many kilograms of sugar does it sell every week?
And an answer: 2
So how you got the answer?
A total of 20 x 100 = 2000 grams are sold every week. Since 1 kilogram is equal to 1000 grams, then 2000 / 1000 = 2 kilograms of sugar are sold every week.
