Re: Average speed problem

First of all, how far away is Paris from the Louvre?

**I** was under the impression that the Louver was **in** Paris!

As was I, I just expected that the OP meant something like the distance between the Louvre to the centre of Paris...

Re: Average speed problem

let the distance = $\displaystyle d$

$\displaystyle x = \frac{d}{t_1} \implies t_1 = \frac{d}{x}$

$\displaystyle t_2 = \frac{d}{x-3}$

$\displaystyle t_1 - t_2 = \frac{d}{x} - \frac{d}{x-3} = \frac{4}{3}$

plug in $\displaystyle d$ (once you find out what it is) and solve for $\displaystyle x$
