this may because Kayla will not swim 2 laps every minute. The 16 minutes may be reached because she may have swam only one lap per minute and then gradually made it up to 2 per minute

Answer:

It really takes her 6 min

Step-by-step explanation:

We can solve this problem easily using cross-multiplication. If she swims 2 laps per minute, then how many minutes will it take her to swim 12 laps?

So in order to use cross-multiplication, let's convert the word problem into ratios:

[tex]\frac{2laps}{12laps}=\frac{1min}{x}[/tex]

Now, we only need to solve the previous equation for x.

Hence, isolating x, we get:

[tex]x=\frac{12laps}{2laps} *1min=6*1min=6min[/tex]
