The missing value depends on the speed of jonas to total miles covered by jonas.......if we were to assume that he jogged up the hill at a distance of 15minutes then the trip took him 42 min in total so the remaining travel time would be 27 minutes .....lets say he is walking down the hill at .5 miles per min,.. you shpuld multiply by 27 by .5 which is 13.5
To find the length of a square given the area, we just need to take the square root of the area given. The sqrt of 36 is 6, so each side is 6 inches. :)
