Help, I am totally clueless on this.

**Reiny**, Thursday, February 5, 2009 at 12:20amlet her time walking be t hours

then the distance she walked = 3t miles

let her time jogging back home be 1/4 - t hours

so the distance she jogged = 6(1/4 - t)

but aren't those two distances the same ?

so...

3t = 6(1/4 - t)

I am sure you can solve this for t, then sub that value back into 3t to get the distance.

**Joy**, Thursday, February 5, 2009 at 12:38amWait, I don't get it.

I solved

3t = 6 (1/4 - t)

and got 11.66666666666....

and then what do I do?

..or did I do that wrong?

**Reiny**, Thursday, February 5, 2009 at 12:47am3t = 6 (1/4 - t)

3t = 3/2 - 6t

9t = 3/2

t = 3/18 = 1/6

then 3t, which was the distance

= 3(1/6) = 1/2

so the distance is 1/2 mile

check:

time walking = 1/2 ÷ 3 = 1/6 hour

time jogging = 1/2 ÷ 6 = 1/12 hour

1/6 + 1/12 = 2/12 + 1/12 = 3/12 = 1/4 hour
