What is the Formula for Distance?

To find out how far an object has traveled (Distance), you simply need to multiply how fast the object is moving (Speed) by how long it has been moving for (Time).

• Distance (d): Usually measured in kilometers (km) or meters (m).
• Speed (s): Usually measured in km/h or m/s.
• Time (t): Usually measured in hours (h) or seconds (s).

Let's apply the formula to a real-world problem: Question: A train is traveling at a constant speed of 80 km/h. How much distance will it cover if it drives for 3 hours? Solution:

• Speed = 80 km/h
• Time = 3 hours
• Distance = Speed × Time
• Distance = 80 × 3 = 240 kilometers. The train will travel exactly 240 km.

You can use this single formula to find the other two variables simply by using basic algebra:

1. If you need to find Distance: D = S × T
2. If you need to find Speed: S = D / T
3. If you need to find Time: T = D / S Crucial Rule: Always ensure your units match! You cannot multiply a speed in 'km/h' by a time in 'minutes'. You must convert the minutes into hours first.
