Write a program to display MPH (Miles per Hour). Create a function to calculate the MPH. Ask the user for the number of miles driven and the number of minute it took to drive that many miles. Validate that both the number of miles and the number of minutes is a positive, non-zero number. Pass both the number of miles and the number of minutes to the function, and have the function return the MPH.

In Python:

def MPH(miles,minutes):

   mph = round(60 * miles/minutes,1)

   return mph

miles = float(input("Miles: "))

minutes = float(input("Minutes: "))

if miles>0 and minutes>0:

   print("MPH: ",MPH(miles,minutes))

else:

   print("Positive inputs only")

Explanation:

This defines the function

def MPH(miles,minutes):

This calculates mph rounded to 1 decimal place

   mph = round(60 * miles/minutes,1)

This returns the calculated mph

   return mph

The main begins here

This gets input for miles    

miles = float(input("Miles: "))

This gets input for minutes

minutes = float(input("Minutes: "))

If miles and minutes are positive

if miles>0 and minutes>0:

This calls the MPH function

   print("MPH: ",MPH(miles,minutes))

If otherwise, this prompts the user for positive inputs

else:

   print("Positive inputs only")

what? ? i don't get it
