Miles per (divided by) hour/s. First you must convert 66 seconds into hours. There are 3600 seconds in an hour, so you divide 66 by 3600 to get hours which is .01833333 hours. So you divide 1.6 miles by .01833333 hours and you get 87.27 miles per hour.

is the correct answer. I divided the 3600 by 66 then times 1.6 to arrive at the same answer.

Hope these services trenches I'm designing for the new fiber optic install don't hit any current infrastructure.
