train a
answer the questions below about the trains.
(a) what is the speed of each train?
train a: m/s

Explanation:

Step1: Recall speed formula

Speed $v=\frac{d}{t}$, where $d$ is distance and $t$ is time.

Step2: Select two - point on graph

From the graph of Train A, when $t = 1\ s$, $d = 60\ m$; when $t = 2\ s$, $d = 120\ m$.

Step3: Calculate speed

$v=\frac{120 - 60}{2 - 1}=\frac{60}{1}=60\ m/s$

Answer:

$60$
