$2880$ $2880$ meters or $2.88$ $2.88$ kilometers.

Distance is given by the equation:

$d = s \cdot t$ $d=s*t$

where:

$d$ $d$ is the total distance traveled

$s$ $s$ is the speed of the person in this case

$t$ $t$ is the time taken

Here: $t=40 \ "min"=2400 \ "s"$

$:.d=(1.2 \ "m")/(color(red)cancelcolor(black)"s")*2400color(red)cancelcolor(black)"s"$

$=2880 \ "m"$

$=2.88 \ "km"$
