A man runs 400 meters north with a speed of 3 meters/second. How long does it take him to complete his trip? Answer in seconds. Round your answer to 3 decimal places. *

133.333 s

Explanation:

From the question given above, the following data were obtained:

Displacement = 400 m North

Velocity (v) = 3 m/s

Time (t) =?

Thus, we can obtain the time taken for the man to complete his trip as shown below:

Velocity = Displacement /Time

3 = 400/time

Cross multiply

3 × time = 400

Divide both side by 3

Time = 400/3

Time = 133.333 s

Therefore, it will take the man 133.333 s to complete his trip.
