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:

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.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
