The task for this question is to write MATLAB code and test a function that converts a distance in miles to a distance in kilometres. The relationship between the two values is given by: D$\_($km$)=1\mathrm{.}60934$D$\_($m$)$ where D$\_($km$)$ is a distance with units of kilometres and D$\_($m$)$ is a distance with units of miles. a$)$ Create a function whose input is a distance with units of miles and whose output is a distance with units of kilometres. Your function should be contained in a separate file with an appropriate name. b$)$ Write a short program that tests your function. The program should Prompt the user to input a distance in units of miles, Use your function from part $($a$)$ to convert the distance to kilometres, Provide the following sentence as output: "A value of x miles is equivalent to a distance of Ykm $."$ where x and Y are the input and outputs for the function respectively.
