Please help me out with how to do this, new to programming. Using Python

Problem 1 (2pts): Write a step-by-step algorithm that calculates the average of 3 floating point numbers (numbers with a fractional part). You can select three hard-code floats or ask the user for the numbers. Once you have written your algorithm, implement it in a Python program. Problem 2 (2pts): Assuming there are no accidents or delays, the distance that a car travels down the interstate can be calculated with the following formula: Distance = Speed * Time A car is traveling at 70 miles per hour. Write a program that displays the following: The distance the car will travel in 6 hours The distance the car will travel in 10 hours The distance the car will travel in 15 hours Label your output using a descriptive text explaining the program results to the user
