Mr. Smith can swim 5 laps of the school pool in 3 minutes, Mr. Moton can swim 6 laps in 4 minutes, Mr. Stanley can swim 4 laps in 2 minutes. Who is the fastest swimmer?

Mr Stanley

Step-by-step explanation:

You want to figure out the time it takes to do 1 lap for each person:

Mr Smith 1 Lap time = 3 : 5 = 0.6 minutes per lap

Mr Moton 1 Lap time = 4 : 6 = 0.666 ... minutes per lap

Mr Stanley 1 Lap time = 2 : 4 = 0.5 minutes per lap

Mr. Stanley

Step-by-step explanation:

L. C. M. of 5,6,4=60

2 | 5-6-4

| 5-3-2

L. CM.=2*5*3*=60

let the laps be 60

Smith can run 60 laps = (3/5) * 60=36 min.

Moton can run 60 laps = (4/6) * 60=40 min.

Stanley can run 60 laps = (2/4) * 60=30 min.

so Stanley is the fastest swimmer.
