Question

what was the record time of usain bolt during the 100 - meter event in 2009 if he ran 10.44 m/s? 1000 seconds 10 seconds 8 seconds 1044 seconds

Explanation:

Step1: Usar fórmula de velocidad

La velocidad $v=\frac{d}{t}$, donde $v$ es la velocidad, $d$ es la distancia y $t$ es el tiempo. Re - arreglamos para encontrar $t$, entonces $t = \frac{d}{v}$.

Step2: Sustituir valores

Tenemos $d = 100$ m y $v=10.44$ m/s. Entonces $t=\frac{100}{10.44}\approx9.58$ s, lo más cercano es 10 s.

Answer:

B. 10 segundos
