Question

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

Answer 1

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
`(d)/(44)`

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:

`\text { distance }= speed * time`

Here time = 8 second,

Substituting the values we get,

`\begin{array}{l}{\rightarrow \text { distance travelled }=44 * 8} \\\\ {\rightarrow \text { distance travelled }=352 \text { feet }}\end{array}`

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

Here distance = "d"

`\text { time }=\frac{\text { distance }}{\text { speed }}`

`\text { time }=(d)/(44)`

Summarizing the results:

a) Distance = 352 feet

b) time taken =
`(d)/(44)`
