Classic Apple II Games You Can Play Without an Emulator

You can play classic Apple II games without an emulator by using an original Apple II computer, an Apple IIe or IIc with a floppy disk or hard drive, or a modern re-release of the game for a current platform. The most practical options are original hardware, a Flash drive-based storage solution, or official ports and remasters sold on modern stores. This article explains each route, what you need, and how to get started.

Formula

The calculator above works out your average pace and speed for a run, ride, or walk. You enter the total time and the distance covered, and it returns your pace in minutes per kilometer and your speed in kilometers per hour. The formulas are:

Pace (min/km) = Total time (minutes) ÷ Distance (km)

Speed (km/h) = Distance (km) ÷ (Total time (minutes) ÷ 60)

Where total time is in minutes, distance is in kilometers, pace is in minutes per kilometer, and speed is in kilometers per hour. If you measure distance in miles, convert miles to kilometers by multiplying by 1.60934 before using the calculator.

Worked Example

Using the default values: you finish a 10 km run in 50 minutes. First, calculate pace:

Pace = 50 ÷ 10 = 5.00 min/km

Then calculate speed:

Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator shows an average pace of 5.00 min/km and an average speed of 12.00 km/h. That matches the block output above.

When to Use This Calculator

Use this calculator when you want a quick, consistent way to compare effort across different distances. Runners often use pace to set training targets, while cyclists and walkers may prefer speed. The key advantage is that it standardizes your output so you can track improvements over time. For example, if you run 5 km in 30 minutes, your pace is 6.00 min/km and speed is 10.00 km/h. If you later run 10 km in 55 minutes, your pace is 5.50 min/km and speed is 10.91 km/h, showing a clear improvement.

How to Read the Result

The first output, pace, is the headline number. A lower pace means faster running. Speed is the inverse: a higher speed means faster movement. Both are useful depending on context. Runners typically think in pace (min/km or min/mile), while cyclists and drivers think in speed (km/h or mph). If you are used to minutes per mile, multiply the pace in min/km by 1.60934 to get min/mile. For example, 5.00 min/km equals about 8.05 min/mile.

Common Mistakes

• Mixing units: Entering distance in miles but time in minutes gives a pace in min/mile, but the calculator assumes kilometers. Convert miles to kilometers first.
• Using seconds: If you enter time in hours and minutes but not as total minutes, the result will be wrong. Convert everything to minutes first.
• Rounding too early: Rounding intermediate values can shift the final result. Let the calculator do the full calculation, then round the output.

Limitations of the Formula

This is a simple average calculation. It does not account for elevation gain, terrain, stops, or wind. Your actual effort may vary even if the average pace is the same. For interval training, you would need separate calculations for each segment. The formula assumes constant speed, which is rarely true in practice, but it is still a useful baseline for planning and tracking.

Frequently Asked Questions

Can I use this for walking or cycling?

Yes. The math works for any activity where you cover a distance in a certain time. Just enter the total time and distance for your walk or ride.

How do I convert pace to speed?

Speed = 60 ÷ pace (in minutes per kilometer). For example, a pace of 5 min/km gives a speed of 12 km/h. The calculator does this for you.

What if I run on a treadmill?

Treadmill distances are usually shown in miles or kilometers. Use the same formula. Note that treadmill running may differ slightly from outdoor running due to lack of wind resistance and belt speed.

Is a lower pace always better?

For a given distance, yes. A lower pace means you covered the same distance in less time. However, for training, you may intentionally run at a slower pace for recovery runs.

Can I use this for a marathon?

Yes. Enter the total finish time and the marathon distance (42.195 km). The calculator will give your average pace and speed for the entire race.
