First arrange in ascending order of time:-
7, 8, 10, 12, 14, 15, 18, 20, 26, 30, 30, 30, 35, 35, 42, 55
MOde is the value occuring mos = 30.
Median is the mean of 2 middle numbers = (20 + 26) / 2 = 23
Mean = sum of the 16 numbers / 16 = 387/16 = 24.2
Based on property of triangles, if two of the three sides are exactly doubled, so will the resulting length. Both answers are 18.
