Answer 2

Answer:

Speed of the horse in km/hour = 72km/hour

Step-by-step explanation:

Given,

Distance traveled by the horse in 10 seconds = 200m

To find,

The speed of the train

Solution:

Recall the formula,

$Speed = \frac{Distance \ traveled}{time \ taken}$

1km = 1000m

1hour = 3600seconds

Here, distance traveled by the horse = 200m.

Since 1000m = 1km,

200m = $\frac{1}{1000}X200$ = $\frac{1}{5}$km

Time taken to travel 200m = 10s.

Since 3600seconds = 1 hour

10 seconds = $\frac{1}{3600} X10$ = $\frac{1}{360}$hours

Substituting the value of distance and time, we get

Speed = $\frac{\frac{1}{5} }{\frac{1}{360} }$ = $\frac{360}{5}$ = 72km/hour

Hence,

Speed of the horse in km/hour = 72km/hour
