answer please

Just multiply the two together:

2.9 X .57=1.653 miles Marta walked.

Maybe use your brain and not ask the internet for the answer to all your easy math problems.

Let $w$ equal number of miles Martha walked

$\frac{2.9mi}{1hr}=\frac{w}{0.57hrs}$

$1hr\times w=0.57hrs\times2.9mi$

$1hr\times w= 1.653mi/hr$

$w=1.653mi$

Martha walked for 1.653 miles.
