[Question]: Samuel is driving to San Francisco’s Comic-Con in his car and he needs to travel 600 miles to the hotel where he made a reservation. At first, he drives at 50 miles/hour for 3 hours straight, then he speeds up to 80 miles/hour for 4 hours. How far is he from the hotel?
[Answer]: At first at 50 miles / hour he travels 50 miles / hours * 3 hours = 150 miles. After that, he speeds up, traveling 80 miles / hours * 4 hours = 320 miles. He travels a total of 150 miles + 320 miles = 470 miles. He is 600–470 = 130miles from the hotel.
So the answer is 130.

[Question]: Mrs. Kaplan has 1/4 as many pizza slices as Bobby has. If Bobby has 2 pizzas and each pizza has 6 slices, how many slices does Mrs. Kaplan have?

[Question]: Carla is taking attendance for her sixth-grade class. She knows that 2 students are in the restroom, and one less than three times that number of students are absent. If there are four rows with six desks each that are all 2/3 full, how many students does Carla teach, including the ones in and out of the classroom?
[Answer]:
First find the number of absent students: 2 students * 3 - 1 = 5 students. Now find the number of students in each row of desks: 6 desks / row * 2 students / 3 desks = 4 students / row. Now find the number of students in all the rows: 4 rows * 4 students / row = 16 students. Now add the students that are absent or in the bathroom: 16 students + 2 students + 5 students = 23 students.
So the answer is 23.
