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.

Cara menggunakan kalkulator ini

  2. Enter the other two values in those units, then press Calculate.

Contoh berserta jalan kerja

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.

Soalan lazim

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.
