Problem 3 A radar speed gun is a device used in law-enforceme✗measure the speed of moving vehicles in miles per hour. The measured speeds are supposed to be stored in a file, one number per line, as follows: 65.6 70.2 54.9 Unfortunately, due to an intermittent fault, occasionally multiple numbers are written on a single line as follows: 73.2 65.6 69.8 Furthermore, occasionally the radar gun outputs a single stray character such as: 67.9z, 6$4.9, or a3.9, to illustrate just a few. Given a file that has radar speed gun readings, write a function averageSpeed() to calculate the average of the numbers in the file. Your code must adhere to the following specifications: a. Prompt the user for the name of the input file to process. When the user enters a nonexistent file name, give the user a second chance. After two wrong entries in a row, quit the program with an appropriate message. b. Ignore numbers containing stray characters. Ignore any reading for slow vehicles moving at 2 miles per…
