Answer:

#"16 hours"#

Explanation:

Solve it using the formula

#"Speed" = "Distance"/"Time"#

#"t" = "Distance"/"Speed"#

#color(white)("t") = (4.00 × 10^7\ "m")/"694 m/s"#

#color(white)("t") = 5.76 × 10^4\ "s"#

#color(white)("t") = 5.76 × 10^4\ cancel"s" × "1 hr"/(3600 cancel"s")#

#color(white)("t") = 16\ "hr"#
