Answer:
The answer is 200 s
Explanation:
To find the duration or time taken we use the formula
[tex]t = \frac{d}{v} \\ [/tex]
where
d is the distance
v is the velocity
From the question
d = 800 m
t = 4 m/s
We have
[tex]t = \frac{800}{4} \\ [/tex]
We have the final answer as
200 s
Hope this helps you
