Jonas jogged up the hill at an average rate of 1/16 of a mile per minute and then walked down the hill at an average rate of 1/12 of a mile per minute. the round trip took him 42 minutes. what is the missing value in the table that represents the distance of the trip down the hill?

The missing value in the table that represents the distance of the trip down the hill depends on the speed of Jonas and to total miles covered by Jonas. In the question above the speed and total distance was not mentioned but if we're to assume that Jonas jogged at a speed of 1 mile per minute up to the hill at a distance of 15 miles, Jonas covered the area in 15 minutes. the trip took him 42 minutes in total, so the remaining travel time down the hill is 27 minutes, let us say that the speed of Jonas walking down the hill is 0.5 miles per minute. To equate the travel of Jonas walking down the hill it should be 27 multiply by 0.5 so that answer is 13.5 miles is the distance of the trip going down the hill.
