Answer:
the distance traveled by the dog is 27.18 m.
Explanation:
Given;
initial velocity of the dog, u = 7.92 m/s
final velocity of the dog, v = 3.22 m/s
time of motion, t = 4.88 s
The distance traveled by the dog is calculated as;

Therefore, the distance traveled by the dog is 27.18 m.
In this question, you are given the volume( 13.3ml) and the mass(8.86) of the gasoline. You are asked to determine the density. Density is calculated by dividing mass by volume. Then the calculation would be:
Density= mass/ volume
Density= 8.86g/13.3ml= 0.666g/ml
