Well, #"1 mile"-=1.609*km#

And so we got....

#65.0*"mile"*hr^-1xx1.609*km*"mile"^-1=104.6*km*"hour"^-1#

And further....#104.6*km*"hour"^-1-=#

#(104.6*km)/(cancel"hour"xx60*cancel"minutes"*cancel"hour"^(-1)xx60*s*cancel"minute"^-1)=#

#=0.029*km*s^-1#...confused yet?

0.03 km/sec

1 mile is 1.609 km.

So 65 miles is 65 x 1.609 = 104.585 km.

And an hour is 3600 seconds.

So, you have 104.585 km per 3600 seconds, or 104.585 / 3600 = 0.03 km per sec.
