Answer 1

1)150-70=80(м/мин)

2)400/80=5(мин)

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 / Speed

Given that the distance between the dog and the owner is 400 meters, and the dog's speed is 150 meters per minute while the owner's speed is 70 meters per minute, we can substitute these values into the formula to find the time it takes for the dog to catch up to the owner.

Time = 400 meters / (150 meters per minute - 70 meters per minute)

Simplifying the equation:

Time = 400 meters / 80 meters per minute

Calculating the result:

Time = 5 minutes

Therefore, it will take the dog approximately 5 minutes to catch up to the owner.
