Colton is judging the egg-and-spoon race at the Silverwood Park Spring Fair. Participants run with an egg on a spoon as fast as they can toward the finish line 60 feet away. Colton is keeping track of the distance each participant runs before dropping the egg. The table shows the results of the first race. Distance (feet) Number of participants 0-10 9 11-20 7 21-30 5 31-40 3 41-50 4 51-60 2 Based on the data, estimate how many of the next 20 participants will run 30 feet or less before dropping the egg. If necessary, round your answer to the nearest whole number. participants​
