Answer:
His average speed is 3 meters per second.
Explanation:
The average speed is given by:
[tex] \overline{v} = \frac{d_{T}}{t_{T}} [/tex]
Where:
[tex]d_{T}[/tex]: is the total distance
[tex]t_{T}[/tex]: is the total time
If he can now push the weight 75 meters in 25 seconds we have:
[tex]d_{T}[/tex] = 75 m and [tex]t_{T}[/tex] = 25 s
Hence, his average speed is:
[tex] \overline{v} = \frac{d_{T}}{t_{T}} = \frac{75 m}{25 s} = 3 m/s [/tex]
Therefore, his average speed is 3 meters per second.
I hope it helps you!
