#"11.05 m/s"#

Explanation:

#"Average speed" = "Total distance"/"Total time"#

#color(white)("Average speed") = "442 m"/"40 s"#

#color(white)("Average speed") = 11.05\ "m/s"#

#11.05# meters per second

Explanation:

Average speed is given by the equation:

#bars=d/t#

where:

  • #d# is the total distance traveled

  • #t# is the total time taken

So, we get:

#bars=(442 \ "m")/(40 \ "s")#

#=11.05 \ "m/s"#
