Question

6.5.1: Functions: Factoring out a unit-conversion calculation.

PYTHON CODING

Write a function so that the main program below can be replaced by the simpler code that calls function mph_and_minutes_to_miles(). Original main program:

miles_per_hour = float(input())
minutes_traveled = float(input())
hours_traveled = minutes_traveled / 60.0
miles_traveled = hours_traveled * miles_per_hour

print('Miles: %f' % miles_traveled)

Sample output with inputs: 70.0 100.0

Miles: 116.666667

Answer 1

# Function written to simplify main code

def mph_and_minutes_to_miles(miles_per_hour, minutes_traveled):

    hours_traveled = minutes_traveled / 60.0

    miles_traveled = hours_traveled * miles_per_hour

    return miles_traveled

miles_per_hour = float(input())

minutes_traveled = float(input())

print('Miles: %f' % mph_and_minutes_to_miles(miles_per_hour, minutes_traveled))
