#"469.5 m"#

Explanation:

Time taken to hit the ground

#"t" = sqrt(("2H")/"g") color(white)(...)[∵ "Initial velocity along vertical is zero"]#

#"t" = sqrt(("2 × 300 m")/("9.8 m/s"^2)) = 7.825\ "s"#

Along horizontal there is no acceleration. So, horizontal distance travelled by it

#"D = v × t = 60"\ "m"/cancel"s" × 7.825 cancel"s" = "469.5 m"#
