Answer:

128 s

Explanation:

The distance, speed and time are related as;

[tex]Distance=Speed\times Time[/tex]

Given that the speed = 5 m/s

Distance = 640 m

Time = ?

So,

[tex]Distance=Speed\times Time[/tex]

[tex]640\ m=5\ m/s\times Time[/tex]

[tex]Time=\frac {640\ m}{5\ m/s}=128\ s[/tex]

Thus, Garza takes 128 s to travel 640 m at 5 m/s speed.
