Answer:
Rita = 300
John = 900
Rodell = 925
Step-by-step explanation:
rita = x (let
john = 3x ( john swims three times more than rita
rodell = 25 + 3x ( rodell swims 25 more than john
x + 3x + 25 + 3x = 2125
or, 7x + 25 = 2125
or, 7x = 2125 - 25
or, x = 2100/7
x = 300
hence,
x = 300
3x = 3 × 300
= 900
25 + 3x = 25 + 900
= 925
