[Question]: Mike began to train to play basketball every day for a tournament. One day he plays a maximum of 2 hours. After a week of training, he increased the maximum time to 3 hours. How many hours did Mike train during the first two weeks?
[Answer]: One week is 7 days, so for one week, Mike trained for 7 * 2 = 14 hours. The second week he began to train for 3 hours a day, so he trained for 7 * 3 = 21 hours. That means Mike in total trained for 21 + 14 = 35 hours.
So the answer is 35.

[Question]: Lilibeth and her friends go strawberry picking. Lilibeth fills 6 baskets where each basket holds 50 strawberries. If three of Lilibeth's friends pick the same amount as her, how many strawberries do Lilibeth and her friends pick in all?
[Answer]: Lilibeth picks 6 x 50 = 300 strawberries. There are 1 + 3 = 4 of them who are picking strawberries. Therefore, they pick a total of 300 x 4 = 1200 strawberries.
So the answer is 1200.

[Question]: Teresa scored 70 marks in science, 80 in music, 85 in social studies, and the physics exam, which was the hardest test that Teresa had ever taken in her entire life, she scored half as many marks as she scored in music. Calculate the total marks Teresa scored in all the subjects.
[Answer]:
The total marks of science and music are 70 + 80 = 150. When you add the marks she scored in social studies, the full marks become 150 + 85 = 235. She scored half as many marks in physics as she scored music, totaling 1 / 2 * 80 = 40 marks. When you add the marks she scored in physics to the total marks of the other subjects, the full marks become 235 + 40 = 275.
So the answer is 275.
