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.
