Question 186893
</pre><font size=4><b>
Let {{{x}}}= amount of time running
So, {{{3x}}}= amount of time swimming (3 times that of running)
It follows----->{{{x+3x=8hrs}}}, EQN 1
{{{4x=8hrs}}}---->{{{cross(4)x/cross(4)=cross(8)2/cross(4)}}}
{{{highlight(x=2hrs)}}}, amount of time running
Also, {{{3*2=highlight(6hrs)}}}, amount of time swimming
Going back EQN 1:
{{{2+3*2=8hrs}}}
{{{2+6=8hrs}}}
{{{8hrs=8hrs}}}
Thank you,
