Answer:
The correct answer , velocity = 7.14 m/s
Step-by-step explanation:
Formula:
Velocity = Distance/Time
The common units are km/hr and m/s
It is given that, a runner that complete 400 meters in 56 seconds
From the given information we get,
Distance = 400 m and time = 56 s
To find the velocity
Velocity = Distance/Time = 400/56 = 7.14 m/s
Therefore the correct answer , velocity = 7.14 m/s
