Answer:
5000 s
Step-by-step explanation:
Mr. Nguyen is moving in uniform motion (constant speed), therefore the distance he covers is given by the equation:
![d=vt](https://img.qammunity.org/2020/formulas/physics/middle-school/u8icp35v1hbarmduh3luj1ggc5xhmglpnp.png)
where
d is the distance
v is the speed
t is the time taken
Here we have
d = 10000 m
v = 2 m/s
Solving for t, we find the time taken to cover this distance:
![t=(d)/(v)=(10000)/(2)=5000 s](https://img.qammunity.org/2020/formulas/physics/middle-school/kqooil5yv3dy674zmq1b02dnnjx8cwv9jv.png)
