Help with basic problem

If I walk from point A to point B, with pace length of C, how many steps must I take to go from A to B, to be within 0.2m of B. Plot step size against number of steps required,

Answer 1

[Andrew Reibold]

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.

So ceil is a "ceiling" function? Thanks
