Geesh folks, this is basic stuff.

Yes the "per" implies division, but you've got it backwards. "meters per

100Km" means "the number of meters in 100Km", or 100Km / 1m.

Then you are confused about the XXeYY notation. As far as I know, this came

from early attempts to express scientific notation in linear text,

specifically in Fortran floating point values. XXeYY means "XX times ten to

the power of YY", or "XX * 10**YY" (where hopefully it's obvious to everyone

that ** is the exponent operator). So 10e5 = 10 x 10**5 = 1,000,000, which

is wrong since you were tring to express 100,000.

Other than that the 10 should be a 1 and the -5 should be a 5 it's perfect.

The correct answer is 100,000 or 10**5 or 1e5.
