Speed distance Time calculation formula Triangle

⚡ Speed, Distance, Time Calculator & Formula Triangle

In UK GCSE Maths and Physics, calculating speed, distance, or time is a core skill. Use the interactive calculator below by choosing what you want to find, entering your values, and watching how the Formula Triangle derives the solution step-by-step!

Distance (d):

Time (t in hours):

S T

To find Speed: Cover ‘S’ in the triangle. You are left with Distance (D) divided by Time (T).

Calculated Result: 60 km/h

Keep these core formulas and unit conversion rules handy for GCSE Maths and Physics problems.

1. Finding Speed (v)

v = Distance ÷ Time (d ÷ t)

Unit: km/h, mph, or m/s

2. Finding Distance (d)

d = Speed × Time (v × t)

Unit: km, miles, or meters

3. Finding Time (t)

t = Distance ÷ Speed (d ÷ v)

Unit: Hours, minutes, or seconds
