Question 170345
label the distance the car going east traveled x and so the distance between the cars would be labeled as x+5. since you have a right triange you can use the pathagorean theorem with one leg 15,the other leg x and the hypothenuse x+5

so write you equation and solve for x:{{{15^2+x^2=(x+5)^2}}} 
:
{{{225+x^2=x^2+10x+25}}}
:
10x=200
:
{{{highlight(x=20)}}} distance the car east traveled
