Question

Lysera enjoys exploring her land on horseback with its lush green valleys and ancient forests. She can cover a great deal of ground on her horse, Princess Grey Dawn, traveling at 9 km/h. Unfortunately Lysera has allergies. How far would Lysera and Princess Gray Dawn have moved while Lysera’s eyes were shut for 0.50 s during a hard sneeze? (answer in kilometers)

Answer 1

Answer:

0.00125 km.

Step-by-step explanation:

Given,

• Speed of the horse on which princess travelling, v = 9km/h

• Time taken by Lysera to sneeze = 0.5 s

As we know

     1 hour = 3600 seconds

$=>\ 1\ second\ =\ \dfrac{1}{3600}\ hour$

$=>\ 0.50 second\ =\ \dfrac{1}{3600}\times 0.50$

                             $=\ 1.38\times 10^{-4}\ hour$

So, time taken by Lysera to sneeze can be given by,

$t\ =\ 1.38\times 10^{-4}\ hour$

According to definition of speed,

$Speed\ =\ \dfrac{distance}{time}$

=>distance = speed x time

                  $=\ 9\ km/h\times 1.38\times 10^{-4}\ hour$

                  = 0.00125 km

Hence, Princess Gray down will moved by 0.00125 km.
