The molecules in the jar are moving around at different speeds. Calculate the average speed of the molecules if the
individual speeds are:
1, 2, 3, 2, 7, 4, 5, 6, 6, 4
1 + 2 + 3+2 +7+4+ 5+ 6 + 6 + 4= 40
40/ 10=4
The average speed is 4
1 + 2 + 3 + 2 + 7 + 4 + 5+ 6 + 6 + 4= 40
40/4= 10
The average speed is 10
1*2*3*2*7*4*5*6*6*4= 241,920
241,920/ 10=4
The average speed is 24,192
1 + 2 + 3 + 2 + 7 + 4 + 5 + 6 + 6 + 4= 40
The average speed is 40

Can you guys me with question no. 5!
