[Question]: Laura took six trips to park. On each trip, she spent 2 hours at the park and an additinal 30 minutes walking to and from the park. What percentage of the total time she took for her trips to the park did Laura spend in the park?
[Answer]: During 6 days, Laura would spend 2 * 6 = 12 hours in the park. If it takes 30 minutes (or 0.5 of an hour) walking to and from the park, then for the six trips, it would take her an additional 0.5 * 6 = 3 hours to walk to and from the park. In total, she would spend a total of 12 + 3 = 15 hours on her six trips. So, the fraction of time spent in the park would be 12 / 15 = 0.8. Thus, converting fraction to percentage, Laura spent 0.8 * 100% = 80% of her trip time at the park.
So the answer is 80.

[Question]: When Mark bought his first tv it was was 24 inches wide and 16 inches tall. It cost $672. His new tv is 48 inches wide and 32 inches tall and costs $1152. How much more expensive as measure by cost per square inch, was his first TV compared to his newest TV?
[Answer]: His first TV was 384 square inches because 24 x 16 = 384. His first TV cost $1.75 per square inch because 672 / 384 = 1.75. His new TV is 1,536 square inches. It costs $.5 per square inch because 1152 / 1,536 = .5. His old TV cost $1 more per square inch because 1.75 - .75 = 1.
So the answer is 1.

Billy has already run 6 miles because 1 plus 1 plus 1 plus 1 plus 1 plus plus 1 equals 6. Tiffany has already run 7 miles because 2 plus 2 plus 2 plus 1 / 3 plus 1 / 3 plus 1 / 3 equals 7. Billy has to run 1 mile to tie Tiffany because 7 minus 6 equals 1.
So the answer is 1.
