Distance Rate Time Calculator

How to Use This Calculator

This calculator helps you find any of the three values (distance, rate/speed, or time) when you know any two of them. The formula used is:

Distance = Rate × Time

Instructions

1. Enter any two values (Distance, Rate/Speed, or Time)
2. Click the "Calculate" button
3. The calculator will automatically calculate and display the missing value

Examples

• Example 1: If you drove at a speed of 60 miles per hour for 3 hours, what distance did you cover?
  Input: Rate = 60, Time = 3
  Calculation: Distance = 60 × 3 = 180 miles
• Example 2: If you traveled 150 kilometers and took 3 hours, what was your average speed?
  Input: Distance = 150, Time = 3
  Calculation: Rate = 150 ÷ 3 = 50 km/h
• Example 3: If you need to travel 200 miles at a speed of 50 miles per hour, how long will it take?
  Input: Distance = 200, Rate = 50
  Calculation: Time = 200 ÷ 50 = 4 hours

Working Principle

The calculator uses the fundamental relationship between distance, rate, and time:

Distance = Rate × Time

From this formula, we can derive:

• Rate = Distance ÷ Time
• Time = Distance ÷ Rate

This relationship allows you to calculate any one of these three variables when you know the other two.
