Question

Twelve equally spaced holes are to be drilled in a 34 1/4 inch metal strip, after 2 inches are cut off on each end. What is the distance, to the nearest hundredth of an inch, from center to center of 2 consecutive holes? _______ inches

How do I start this?

Answer 1

You have a 30 1/4 inch strip after trimming the ends. You need to specify how close the holes can be to the end of the remaining strip. The diameter of the holes is also necessary, to make sure part of the hole does not go beyond an edge

If the holes are very small and can be drilled right to the edges, you need 11 gaps in 30.25 inches. That would be 2.75 inches between holes.
