As Fórmulas

Velocidade = Distância ÷ Tempo. Distância = Velocidade × Tempo. Tempo = Distância ÷ Velocidade. 300 km a 100 km/h: 3 horas. No Brasil, as rodovias têm velocidade máxima de 80-110 km/h (110 em algumas autoestradas).

Aplicações

Viagens: estime hora de chegada. Corrida: pace. GPS usa essas fórmulas constantemente. A velocidade média real é sempre menor que a de cruzeiro (paradas, tráfego).

⚡ CalcWolf Insight

GPS apps calculate arrival times using this exact formula with real-time traffic adjustments. The speed-distance-time relationship is the most applied physics equation in daily life.
