Answer #1

appl6ing concept of relative velocity

over speed limit = actual velocity - person velocity

person velocity = 70 - 50 = 20 miles per hour

do comment in case any doubt, will reply for sure.. Goodluck

    Speeding Violation Calculator: Design a program that calculates and displays the number of miles per hour over the speed limit that a speeding driver was doing. The program should ask for the speed limit and the driver’s speed. Validate the input as follows: The speed limit should be at least 20 but not greater than 70. The driver’s speed should be at least the value entered for the speed limit (otherwise the driver was not speeding).Once correct data has been...
