Question

A racehorse is running with a uniform speed of 69 km/hr along a straightaway. what is the time it takes for the horse to cover 400 meters?

Answer 1

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

Hope this helps :))

Answer 2

Time, t = 20.87 seconds

Step-by-step 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 :

`v=(d)/(t)`

`t=(d)/(v)`

`t=(400\ m)/(19.16\ m/s)`

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.
