Write an expression that can be used to solve the problem. . . During practice, it took Shawn 27 min to swim 81 laps. If Shawn swam at a constant rate, how long did it take him to complete each lap?. . A.27*81. . . B.27+81. . . C.81/27. . . D.27/81. .
If he takes 27 minutes to swim 81 laps then how many minutes does it take to do one lap? So we need to divide 81 by 27.
C. 81/27
to complete each lap= swim 81 /laps27 min
therefore C is the right option
hope this helps
