#2880# meters or #2.88# kilometers.

Distance is given by the equation:

#d=s*t#

where:

#d# is the total distance traveled

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

#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"#
