steps_required = ceil(((B-.2)-A)/C)
Explanation: Assuming you want to take the minimum amount of steps, the distance you MUST travel is the difference between B-A, with a grace of .2
Divided that distance by your step length, and you get the number of steps (round UP).
I'll let you do the critical thinking for the second part. This sounds like a homework problem.
