Answer:
One way the dog can easily reach the bone is given by the relationship between the dog, the tree, and the bone
The dog can easily reach the bone when the tree is between the the dog and the bone, and the dog was more than 5 meters behind the tree
Therefore the distance the dog can reach in the direction of the bone from its position behind the tree is more than 15 meters and the dog can easily get the bone while the leash is not harmed
Step-by-step explanation:
We are given two variables, distance and volume of gas required to reach the distance.
We are then asked to find the rate of consumption in miles per gallon.
The approach is simply to divide distance by the volume to get the rate per unit gallon.
This means that for each gallon consumed, 24 miles are covered.
24 mpg
