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

Step-by-step explanation:

As long as the runner does not change direction, the velocity would be

Formula

d = r*t

r = d/t

Solution

r = 400 m  / 56 s

r = 7.14 m/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

they can both be solutions depends on the equation
