An animal is running at a rate of 44 ft per sec. ​(a) If the animal runs for 8 ​sec, what is its​ distance? ​(b) If the animal travels d​ ft, what is its​ time

Respuesta :

a) If the animal runs for 8 ​sec, then the distance is 352 feet

b) If the animal travels d​ feet, then the time taken is [tex]\frac{d}{44}[/tex]

Solution:

Given, An animal is running at a rate of 44 ft per sec.

Speed = 44 feet per second

a) To find the distance if animal runs for 8 second:

The relation between speed and distance is given as:

[tex]\text { distance }= speed \times time[/tex]

Here time = 8 second,

Substituting the values we get,

[tex]\begin{array}{l}{\rightarrow \text { distance travelled }=44 \times 8} \\\\ {\rightarrow \text { distance travelled }=352 \text { feet }}\end{array}[/tex]

b) To find the time taken if the animal travels "d" feet:

Here distance = "d"

[tex]\text { time }=\frac{\text { distance }}{\text { speed }}[/tex]

[tex]\text { time }=\frac{d}{44}[/tex]

Summarizing the results:

a) Distance = 352 feet

b) time taken = [tex]\frac{d}{44}[/tex]
