To write the scale without units how far can the bike travel in 5 hour

Answer to Problem 10E
The scale without unit is 1:2000
Explanation of Solution
Given information :
Consider, the question 1mm :2 meterbike can travel 24 miles in 2 hour
Calculations to find the scale without unit it is necessary that the units on both the sides of the ratio are same, there are 1000mm in 1 m.
calculate the number of mmin 2m Therefore,
The expression will be-
Therefore, the ratio without unit is 1:2000

Solving A C = B for C provides youwith the coefficients of a natural cubic spline curve that interpolates these points.Additionally, you have been given A and B, but some elements are missing. Moreover, the last two rowsof A are entirely absent. Your task is to determine and fill in the missing elements. For the last two rows,enforce a zero tangent at the beginning (in p1) and a not-a-knot boundary condition in p2. The matricesA and B are given as follows:Explain how to find the entries of A and B .
