Convert Minutes into Seconds

Calculate the Area of a Triangle

Master mathematical geometric formulas in Python by calculating a triangle's area using base times height divided by two.

1. The Challenge: Time Unit Conversion

Write a Python function convert(minutes) that takes an integer number of minutes and converts it into total seconds.

2. Why It Matters

Unit conversions are common in application development, such as calculating session timeouts, game timers, and API rate limits.

3. The Python Solution

Since there are 60 seconds in 1 minute, multiply the input minutes by 60:

def convert(minutes):
    return minutes * 60

# Testing our function
print(convert(5)) # Output: 300
print(convert(3)) # Output: 180
print(convert(2)) # Output: 120

4. Understanding Python Numeric Types

In Python, multiplying an integer by an integer yields an int (e.g. 5 * 60 == 300). If you multiply by a float (60.0), Python returns a float (300.0).

5. Common Mistakes

• Using Division Instead of Multiplication: Dividing by 60 calculates hours, not seconds! Remember: 1 minute = 60 seconds.
• Handling Negative Inputs: If time cannot be negative in your domain, validate inputs: if minutes < 0: return 0.

6. Next Steps

Use simple arithmetic for unit conversions. Next, let's calculate the area of a triangle!
