Question 57679
you can solve this question by setting up a linear equation,

let our variable be X

since she runs 7 times more than she swims we can state that swimming is x and running is 7x. since biking is 7 times more than running we can say (7)(7x) or 49X. Because the total distance is 232 miles we can set up the equation below.

(x)+(7x)+(49x)=232

because all the terms are alike we can add them together..

57X=232

now you divide both sides by 57 to isolate x

x=4.07017......

so she swims 4.07 miles, she runs (7)*4.07= 28.5 miles and she bikes 28.5*(7)=199.5 miles
