Formula

speed=distancetime\text{speed} = \frac{\text{distance}}{\text{time}}

How far you go in each unit of time.

distance=speed×time\text{distance} = \text{speed} \times \text{time}

Rearranged to find the distance.

time=distancespeed\text{time} = \frac{\text{distance}}{\text{speed}}

Rearranged to find the time.

Come usare questa calcolatrice

  1. Choose what you want to find and the units you are using.
  2. Enter the other two values in those units, then press Calculate.

Esempio svolto

150 km in 2.5 hours

speed = distance ÷ time = 150 ÷ 2.5 = 60 km/h.

In metres per second: 60 × 1000 ÷ 3600 ≈ 16.666667 m/s.

Domande frequenti

How do I remember the formula?

Use the triangle: D on top, S and T underneath. Cover the one you want — D = S × T, S = D ÷ T, T = D ÷ S.

How do I convert km/h to m/s?

Multiply by 5/18 (that is × 1000 ÷ 3600). To go back, multiply by 18/5.
