Question

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

Answer 1

The correct answer , velocity = 7.14 m/s

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

Answer 2

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
