Answer: Constant of Proportionality = 12
===================================================
Explanation:
x = number of swimmers
y = number of laps
k = constant of proportionality
k = y/x
Use any row to find that k = 12
- Row1: k = y/x = 240/20 = 12
- Row2: k = y/x = 216/18 = 12
- Row3: k = y/x = 168/14 = 12
- Row4: k = y/x = 108/9 = 12
The direct proportion equation in the form y = kx turns into y = 12x. This means the number of laps is 12 times that of the number of swimmers. Put another way, each swimmer did 12 laps.
