Question

1. weight distribution on paper plane and hang time: front trial 1: 2 sec, trial 2: 2.5 sec, trial 3: 1.9 sec, trial 4: 2.1 sec, trail 5: 3 sec middle trial 1: 3 sec, trial 2: 2.1 sec, trial 3: 2 sec, trial 4: 1.3 sec, trail 5: 1.5 sec back trial 1: 2 sec, trial 2: 3 sec, trial 3: 1.5 sec, trial 4: 2 sec, trail 5: 1.1 sec graph:

Explanation:

Step1: Calculate average for Front

The formula for average is $\frac{\text{Sum of values}}{\text{Number of values}}$.
For Front: $\frac{2 + 2.5+1.9 + 2.1+3}{5}=\frac{11.5}{5}=2.3$

Step2: Calculate average for Middle

For Middle: $\frac{3 + 2.1+2 + 1.3+1.5}{5}=\frac{9.9}{5}=1.98$

Step3: Calculate average for Back

For Back: $\frac{2 + 3+1.5 + 2+1.1}{5}=\frac{9.6}{5}=1.92$

Answer:

Front: $2.3$ sec, Middle: $1.98$ sec, Back: $1.92$ sec
