Can anyone help me please? (I already posted this once but I forgot the picture)

Answer 1

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.
