What is in this set

The numbers in this set run from 15 to 1,080.
A careful solution takes 2 written steps on average.
The mistake this set invites most often, in 100% of the problems: the two numbers were multiplied; the hours are the distance shared out at so many miles in each of them.
Answers are a whole number.

Drawing 240 problems from this page produced 121 different ones, 50% — so a sheet of 20 will come back to a problem you have seen — there are only so many sensible ones of this kind.
