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?
How many hours did Laura spend in the park? ** During 6 days, Laura would spend 2 * 6 = <<2*6=12>>12 hours in the park.
How many hours did Laura spend walking to and from 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 = <<0.5*6=3>>3 hours to walk to and from the park.
How many hours did Laura spend on her six trips? ** In total, she would spend a total of 12 + 3 = <<12+3=15>>15 hours on her six trips.
What percentage of the total time did Laura spend in the park? ** So, the fraction of time spent in the park would be 12 / 15 = <<12/15=0.8>>0.8.
What percentage of the total time did Laura spend in the park? ** Thus, converting fraction to percentage, Laura spent 0.8 * 100% = 80% of her trip time at the park.
