Question

In a stable, a stable boy takes a horse for exercise
for 40 minutes. If the horse runs for a stretch of
24km, find its average speed.​

Answer 1

Answer:

Average speed is 36 km/h or 10 m/s.

Step-by-step explanation:

Given:

Distance traveled by the horse, $d=24\textrm{ km}$

Time taken by the horse, $t=40\textrm{ min}=\frac{40}{60}=\frac{2}{3}\textrm{ hour}$

Average speed is given as the ratio of distance traveled to that of total time taken.

So, Average speed  is given as:

$v=\frac{d}{t}=\frac{24}{\frac{2}{3}}=\frac{24\times 3}{2}=\frac{72}{2}=36\textrm{ km/h}$

Now, if we want the speed in m/s, then we multiply the speed in km/h by $\frac{5}{18}$. This gives,

Average speed, $v=36\times \frac{5}{18}=10\textrm{ m/s}$

Hence, average speed of the horse is 36 km/h or 10 m/s.
