a) Elapsed time for trial B: 3.0 s

Explanation:

The elapsed time is defined as the difference between the final time and the initial time:

[tex]t_{elapsed} = t_{final}-t_{initial}[/tex]

For trial B, the final time is 4.5 s, while the initial time is 1.5 s, therefore the elapsed time is

[tex]t_{elapsed} = 4.5 s-1.5 s=3.0 s[/tex]


b) Average speed for trial B: 1.3 m/s

Explanation:

The average speed is given by the distance traveled divided by the elapsed time:

[tex]v=\frac{d}{t_{elapsed}}[/tex]

For trial B, the distance traveled is d=4.0 m, while the elapsed time is t=3.0s, therefore the average speed is

[tex]v=\frac{4.0 m}{3.0 s}=1.3 m/s[/tex]
