To find out how far the car would travel in 42 days, you can set up a proportion based on the given information:

[ \frac{{\text{Distance traveled in 14 days}}}{{\text{Time taken in 14 days}}} = \frac{{\text{Distance traveled in 42 days}}}{{\text{Time taken in 42 days}}} ]

[ \frac{{729 , \text{km}}}{{14 , \text{days}}} = \frac{{x , \text{km}}}{{42 , \text{days}}} ]

Solving for ( x ):

[ x = \frac{{729 , \text{km} \times 42 , \text{days}}}{{14 , \text{days}}} ]

[ x = \frac{{729 , \text{km} \times 3}}{{1}} ]

[ x = 2187 , \text{km} ]

Therefore, the car would travel 2187 km in 42 days at the same rate.
