Find the velocity of a runner that complete 400 meters in 56 seconds

7.142m/s

Step-by-step explanation:

Velocity=change is distance/change in time

change in distance=400m-0m=400m

change in time=56-0=56seconds

v=400m/56s

v=7.143m/s

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
