Derail in Modern Warfare III: Map Layout, Routes & Positions

Derail is a large, snow-covered map in Call of Duty: Modern Warfare III that emphasizes long sightlines, verticality, and careful positioning. This article explains the full map layout, the key routes between buildings, and the strongest positions for controlling the flow of combat. You’ll learn where the action concentrates, how to flank effectively, and how to avoid common ambush spots.

Formula

The calculator above works out your average pace and speed when you know the time taken and the distance covered. The formulas are:

Pace (min/km) = Time (minutes) ÷ Distance (kilometers)

Speed (km/h) = Distance (kilometers) ÷ (Time (minutes) ÷ 60)

Where Time is the total minutes elapsed and Distance is the distance traveled in kilometers. Pace tells you how many minutes each kilometer takes; speed tells you how many kilometers you cover in one hour.

Worked Example

Using the default values from the calculator: you spend 10 minutes moving 100 meters (0.1 km).

1. Convert distance to kilometers: 100 m ÷ 1000 = 0.1 km.
2. Pace = 10 min ÷ 0.1 km = 100 min/km.
3. Speed = 0.1 km ÷ (10 min ÷ 60) = 0.1 ÷ 0.1667 = 0.6 km/h.

The calculator shows a pace of 100 min/km and a speed of 0.6 km/h. That is a very slow walking pace, which makes sense for a short distance over a long time.

When to Use This Calculation

Use this pace and speed calculator whenever you have a known distance and time and want a standard metric. Common situations include:

• Walking, jogging, or cycling a measured route.
• Planning a hike where you know the trail length and want to estimate arrival time.
• Comparing your average speed across different training sessions.
• Estimating how long a future trip will take at a similar pace.

The result is a simple ratio, so it works for any distance and time unit as long as you convert to kilometers and minutes first. For imperial users, 1 mile = 1.60934 km and 1 hour = 60 minutes, so the same formulas apply after conversion.

How to Read the Result

A lower pace (min/km) means you are moving faster. A higher speed (km/h) also means faster movement. The two numbers are reciprocals of each other in a sense: pace = 60 ÷ speed, and speed = 60 ÷ pace, when speed is in km/h and pace is in min/km. For example, a 6 min/km pace equals 10 km/h. The calculator gives both so you can use whichever unit you prefer.

If you are training, compare your pace over the same route on different days to see improvement. If you are planning a trip, multiply your expected pace by the total distance to get the total time in minutes.

Common Mistakes and Limits

The most frequent error is mixing units. If you enter distance in miles but time in minutes, the result will be wrong. Always convert miles to kilometers first. Another mistake is rounding too early; for example, rounding 0.1 km to 0 km would break the calculation. Keep at least two decimal places for distances under 1 km.

The formula assumes constant speed, which rarely happens in real walking or running. It gives an average, not a real-time measure. It also ignores stops, terrain, and elevation changes. For hilly routes, the actual time will be longer than the calculation suggests.

The calculator is a pure math tool. It does not account for fitness level, weather, or load carried. Use it as a rough guide, not a precise prediction.

Frequently Asked Questions

How do I convert my pace from min/mile to min/km?
Multiply the min/mile pace by 0.621371. For example, a 10 min/mile pace is 10 × 0.621371 = 6.21 min/km. Conversely, multiply min/km by 1.60934 to get min/mile.

What is a good average walking speed?
A typical walking speed for an adult is around 5 km/h, which is a 12 min/km pace. Brisk walking can reach 6-7 km/h. Running speeds vary widely, but a casual jog is often 8-10 km/h.

Can I use this for cycling or driving?
Yes, the formula works for any moving object. Just enter the distance and time. For driving, you might prefer to enter distance in miles and convert to kilometers, or use a dedicated speed calculator.

Why does the calculator show 100 min/km for the default example?
Because 10 minutes divided by 0.1 km equals 100 minutes per kilometer. That is an extremely slow pace, but it is mathematically correct for the given inputs. The defaults are chosen to show a clear calculation, not to represent a realistic activity.

What if I only know my speed in mph?
Convert mph to km/h by multiplying by 1.60934. Then use the speed formula to find pace: pace = 60 ÷ speed (km/h). For example, 5 mph = 8.05 km/h, so pace = 60 ÷ 8.05 = 7.45 min/km.
