What is Speed?
Speed is a measure of how fast an object moves. It tells us the distance covered in a certain amount of time. The relationship is described by the simple formula:
Speed = Distance ÷ Time
🔹 The Three Building Blocks
- Speed (v) – how fast something travels (km/h, m/s, mph…)
- Distance (d) – how far it moves (km, m, miles…)
- Time (t) – how long the journey takes (hours, minutes, seconds)
🔹 Common Uses
Whether you're planning a road trip, solving physics homework, or calculating your running pace, a speed calculator saves you mental arithmetic and unit conversion headaches.
Answer: Speed = 150 km ÷ 2 h = 75 km/h.
🔹 Unit Conversion Tips
Switching between units is automatic in the tool. Here are a few useful mental conversions:
- 1 km/h ≈ 0.2778 m/s
- 1 mph ≈ 0.447 m/s
- 1 knot ≈ 0.514 m/s
- 1 mile ≈ 1.609 km
FAQ
How do you calculate speed?
Divide distance by time. Make sure units match: if distance is in meters and time in seconds, speed will be in m/s.
What if I know speed and time, but need distance?
Multiply speed by time: Distance = Speed × Time.
Can I use minutes instead of hours?
Absolutely. The calculator accepts minutes and converts everything internally. Just pick the unit you prefer.
