Lenovo does not currently sell a mainstream smartphone with a truly all-screen front, but the company has demonstrated and released concept devices that push toward that goal. The most notable is the Lenovo Z5 Pro, which uses a sliding mechanism to hide the front camera and sensors, achieving a 95.06% screen-to-body ratio. This article explains what “all screen” means in Lenovo’s context, how the technology works, what to consider if you’re shopping, and what alternatives exist.
Formula
The calculator works out your average pace and speed for a run or ride. The formulas are:
- Pace = Finish time (minutes) ÷ Distance (km) — result in min/km.
- Speed = Distance (km) ÷ (Finish time (minutes) ÷ 60) — result in km/h.
Where:
- Finish time (t) – total time taken, in minutes.
- Distance (d) – total distance, in kilometers.
- Pace – time per kilometer, expressed as minutes and seconds (e.g., 5:30).
- Speed – average velocity over the whole distance, in kilometers per hour.
Worked Example
Using the default values: finish time = 50 minutes, distance = 10 km.
- Pace = 50 min ÷ 10 km = 5.0 min/km (i.e., 5:00 per km).
- Speed = 10 km ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.0 km/h.
The calculator shows: Pace = 5.00 min/km and Speed = 12.00 km/h.
When to Use This Calculator
Use this tool when you want to know your average pace for a training run, compare your speed on different routes, or plan a target time for a race. For example, if you want to finish a 10 km race in under 50 minutes, you need a pace faster than 5:00 per km. The calculator works for any distance and time, from a short jog to a marathon, as long as you enter the total time and distance.
How to Read the Results
Pace is given in minutes per kilometer (min/km). A lower number means faster running. Speed is given in kilometers per hour (km/h); a higher number means faster movement. For US users, you can convert: 1 mile ≈ 1.609 km, so 5:00 per km ≈ 8:03 per mile. Many runners prefer to think in pace rather than speed because it directly relates to effort per distance.
Common Mistakes and Limits
- Unit mix-ups: Entering time in hours instead of minutes will give a pace that is 60 times too fast. Always convert hours to minutes (e.g., 1:30:00 = 90 minutes).
- Distance in miles: If you run in miles, convert to km first (miles × 1.609) or the pace will be wrong.
- Rounding: The calculator rounds to two decimal places, which is fine for training. For race planning, you might want more precision, but 0.01 min/km is negligible.
- Limits: The formula assumes constant speed. In reality, your pace varies with hills, wind, and fatigue. The result is an average, not a predictor of splits.
Frequently Asked Questions
How do I convert pace to miles per hour?
First convert pace to minutes per mile (multiply min/km by 1.609), then divide 60 by that number. For example, 5:00 per km → 8:03 per mile → 60 ÷ 8.05 = 7.45 mph.
What is a good pace for a beginner?
A common beginner jogging pace is around 6:30 to 7:30 per km (about 10:30 to 12:00 per mile). This varies widely with age, fitness, and terrain. Use the calculator to find your current average pace and set realistic goals.
Can I use this for cycling or walking?
Yes, the formulas work for any activity where you measure time and distance. For cycling, you might prefer speed in km/h, which the calculator provides. For walking, pace is often slower, like 10–15 min/km.
Why does my GPS watch show a different pace?
GPS devices calculate pace in real-time based on your instantaneous speed and often use “moving time” (excluding pauses). This calculator uses total time, so it includes stops. That’s why your watch may show a faster pace if you take breaks.
How do I calculate pace for a marathon?
Enter the total time you want (e.g., 240 minutes for 4 hours) and the distance (42.195 km). The calculator will give you the average pace needed, like 5:41 per km. Remember that real races involve hills and surges, so aim for a slightly faster pace early on if you tend to fade.
