Answer 1

150-70=80 м/мин,
400/80=5 мин-через 5 минут собака догонит хозяина

Answer 2

Calculation of Time for the Dog to Catch up to the Owner

To calculate the time it takes for the dog to catch up to the owner, we can use the formula:

Time = Distance / Relative Speed

Given: - Distance between the dog and the owner = 400 m - Dog's speed = 150 m/s - Owner's speed = 70 m/s

Let's substitute these values into the formula:

Time = 400 m / (150 m/s - 70 m/s)

Simplifying the equation:

Time = 400 m / 80 m/s

Calculating the time:

Time = 5 seconds

Therefore, the dog will catch up to the owner in 5 seconds.
