Answer 1

No

Average speed of car = 5m/s

Distance run by dog = 20m

Time taken = 5s

problem;

does the dog catches the car = ?

Solution;

let us determine speed of the dog;

   Speed = $\frac{distance}{time} = \frac{20}{5}$ = 4m/s

The average speed of the car is 5m/s

Average speed of the dog is 4m/s

The dog is slower than the car and it will not catch the car at this rate.
