Question

Rosa is building a guitar. The second fret is 33.641 mm from the first fret. The third fret is 31.749 mm from the second fret. How far is the third fret from the first fret?

Answer 1

Explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The distance from first to second fret = 33.641 mm

The distance from second to third fret = 31.749 mm

So, distance from first to third =
`33.641 + 31.749 = 65.39 mm`

Hence third fret is 65.39mm far from first fret. : Answer

Hope it will help :)

Answer 2

65.390 mm

Explanation:

In order to find the distance of the third fret from the first fret, we must sum the distance between the first and the second fret and the distance between the second and the third fret:

`d_(13)=d_(12)+d_(23)`

Substituting the numbers given by the problem, we find

`d_(13)=d_(12)+d_(23)=33.641 mm+31.749=65.390 mm`
