Question

Nala is escaping from the dragon's lair! She is running toward the entrance of the lair at a speed of 9.29.2 meters per second. The entrance is 180180 meters away. The distance dd between Nala and the entrance of the lair is a function of tt, the time in seconds since Nala began running. Write the function's formula.

Answer 1

Answer: Our function will be

`d=180-9.2t`

Explanation:

Since we have given that

Distance of the entrance = 180 meters

Speed of Nala who is running towards the entrance of the lair = 9.2

As we know the "Distance-Speed formula":

`Time=(Distance)/(Speed)\\\\t=(180)/(9.2)\\\\t=19.565\\\\t=19.57\ seconds`

So, our required function will be

`d=180-9.2t`

As we increase the time distance get reduced from 180 which is the distance of the entrance .

Hence, our function will be

`d=180-9.2t`
