Question

1. measure: you can get a more accurate estimate of distance and time using these steps

• use the time slider to position the animal so that its nose is even with the first tree.

record the current time in the table below as time 1.

• position the animal so that its nose is even with the last tree and record time 2.
• subtract the first time from the second to get the time difference.
• record the distance from the first tree to the last. (the trees are 5 meters apart.)

time 1	time 2	time difference (s)	distance (m)

1. calculate: the speed of the animal is equal to the distance divided by the time difference.

a. what is the estimated speed of the animal now? ____

b. is this value close to the speed you calculated before? ____

Explanation:

Step1: Identificar los valores de distancia y tiempo

Supongamos que se han obtenido los valores de Time 1, Time 2 y la distancia entre los árboles es de 5 metros. Calculamos el Time difference como Time 2 - Time 1.

Step2: Aplicar la fórmula de la velocidad

La fórmula de la velocidad $v$ es $v=\frac{d}{t}$, donde $d$ es la distancia y $t$ es el tiempo. Aquí, $d = 5$ metros y $t$ es el Time difference calculado anteriormente.

Answer:

A. Sin conocer los valores reales de Time 1, Time 2 y el Time difference, no se puede dar un valor numérico. Pero si el Time difference es $t$ segundos, la velocidad $v=\frac{5}{t}$ m/s.
B. No se puede responder sin conocer el valor calculado anteriormente.
