Sarah and eva are swimming
use the ratio table to determine who is the faster swimmer

Sarahtime  (min)                    {3 }       5      12    17
distance (meters)        {75}      125   300  425

Eva time  (min)                     {2}    7      10    20
distance (meters)         {52}  182   260  520

 

Sarah:meters over min =75 over 3 = 25 over 1
25 meters per min

Eva :meters over min= 52 over 2 =26 over 1
 26 meters per min

eva is the faster swimming because 26 meters per min is faster then 25 meters per min .

i hope this help
