Respuesta :

Answer:

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

Answer:

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.
