Hello there,
400 meters= 0.4 km
Time= Distance / speed
        = 0.4 / 69
        = 0.0057971014492754 hr
        = 0.35 min

Hope this helps :))

Answer:

Time, t = 20.87 seconds

Explanation:

Given that,

Speed of the racehorse, v = 69 km/h = 19.16 m/s

Distance covered by the horse, d = 400 m

Let t is the time taken by the horse to cover 400 meters. It can be calculated using the definition of speed. Mathematically, the speed is given by :

[tex]v=\dfrac{d}{t}[/tex]

[tex]t=\dfrac{d}{v}[/tex]

[tex]t=\dfrac{400\ m}{19.16\ m/s}[/tex]

t = 20.87 seconds

So, the time taken by the horse to cover 400 meters is 20.87 seconds. Hence, this is the required solution.
