Question: Roberto is out for a hike. He travels uphill at 2 MPH and downhill at 3MPH. The trail is 5 miles long. 60% is uphill and the rest is downhill. How long does it take him to complete it in minutes?
Answer: Step-by-step reasoning process: There is 3 miles uphill because 5 x .6 = 3. This takes him 1.5 hours because 3 / 2 = 1.5. This takes him 90 minutes because 1.5 x 60 = 90. 40% of the trail is downhill because 100 - 60 = 40. There are 2 miles of downhill because 5 x .4 = 2. This takes him 2 / 3 of an hour because 2 / 3 = (2 / 3). This takes him 40 minutes because 60 x (2 / 3) = 40. It takes him 130 minutes in total because 90 + 40 = 130.
So the answer is 130.

Question: In a classroom, there are blue chairs, green chairs, and white chairs. There are 10 blue chairs. The green chairs are 3 times as many as the blue chairs, and there are 13 fewer white chairs than the green and blue chairs combined. How many chairs are there in a classroom?
Answer: Step-by-step reasoning process: There are 10 x 3 = 30 green chairs. The total number of blue and green chairs is 10 + 30 = 40. So, there are 40 - 13 = 27 white chairs. Therefore, there are 40 + 27 = 67 chairs in a classroom.
So the answer is 67.

Question: Madison and Gigi have to run a total of 2400 meters in gym class. The track is 150 meters around. If they each have run 6 laps, how many more laps do they have to run before they reach 2400 meters?
Answer: Step-by-step reasoning process: The have run 12 laps because 6 + 6 = 12. They have run 1,800 meters because 12 x 150 = 1,800. They have 600 more meters to run because 2,400 - 1,800 = 600. The have to run 4 more laps because 600 / 150 = 4.
So the answer is 4.

Step-by-step reasoning process: Selena was charged $24 x 2 = $48 for the steaks. She was charged $3.5 x 2 = $7 for the burgers. She was charged $2 x 3 = $6 for the cups of ice cream. She was charged $48 + $7 + $6 = $61 in total. Therefore, Selena was left with $99 - $61 = $38.
So the answer is 38.
