Speed Formula:
From: | To: |
Definition: This calculator computes speed based on distance traveled and time taken using the fundamental formula S = D/T.
Purpose: It helps travelers, drivers, athletes, and transportation professionals determine speed when distance and time are known.
The calculator uses the formula:
Where:
Explanation: The distance is divided by time to calculate the average speed over that period.
Details: Accurate speed calculation is essential for trip planning, fuel estimation, safety compliance, and performance measurement.
Tips: Enter the distance in miles and time in hours. For minutes, divide by 60 (e.g., 30 minutes = 0.5 hours). All values must be > 0.
Q1: Can I use kilometers instead of miles?
A: Yes, but the result will be in km/h. For mph, convert km to miles first (1 km ≈ 0.621 miles).
Q2: How do I calculate time if I know speed and distance?
A: Use T = D/S. Our calculator can be rearranged for different variables.
Q3: What if my time includes hours and minutes?
A: Convert minutes to decimal hours (e.g., 2 hours 30 minutes = 2.5 hours).
Q4: Does this calculate average or instantaneous speed?
A: This calculates average speed over the given distance and time period.
Q5: How accurate is the calculation?
A: The calculation is mathematically precise, but real-world results may vary due to acceleration/deceleration.
