Question

in c++ Write a program that asks the user for the speed of a vehicle (in miles per hour) and how many hours it has traveled. It should use a loop to display the total distance traveled. The speed traveled should be limited by the fastest speed achieved by a car thus far. Values should not be negative.•Ex: if hours = 3 and speed = 40, then the program should display•Hour 1: Distance Traveled: 40 miles•Hour 2: Distance Traveled: 80 miles•Hour 3: Distance Traveled: 120 miles

continued•Write a program that asks a person for their weight then converts their weight to the weight on the planet of their choice. This program should use a switch. You may have to use google to look up some conversions. •Example: If the user entered a weight of 180 lbs and chose the planet Jupiter. The program should return: “Your weight on Jupiter is 455 lbs.
