1520000 km.

Explanation:

Start by displacing the decimal:

#1.52 * 10^6#

#15.2 *10^5#

#152*10^4#

Now, get four zeroes after that:

#1.52*10^6# mm #= color(green)(1.52 " km")#

Explanation:

#1000# millimeters #= 1 # meter
or written another way:
#10^3# millimeters #= 1 # meter.

#1000# meters #= 1# kilometer
or written another way
#10^3# meters #= 1# kilometer.

Using the standard abbreviations:
#color(white)("XXX")#mm: millimeter
#color(white)("XXX")#m: meter
#color(white)("XXX")#km: kilometer
#1 "km"= 10^3"m" = 10^3 xx(10^3) "mm" = 10^6 "mm"#

If #10^6"mm" = 1 km"#
then
#1.52xx10^6"mm" = 1.52"km"#
