Write a Python program that calculates the estimated active calories burned during a run lasting between 15 and 90 minutes.

Your program should:

• keep asking the user to enter the run duration in minutes until they enter a value that is between 15 and 90 (inclusive)
• calculate the baseline calories burned by multiplying the duration by 7.5
• ask the user if the run was on an incline (expect the user to enter yes if it was)
• if there was an incline, multiply the calculated baseline calories by 1.4
• output the final estimated calories burned.

You should use meaningful variable name(s), correct syntax and indentation in your answer.
