Question

Помогите пожалуйста решить! Шмель и оса полетели с поля в одном направлении. Зная, что шмель летел со скоростью 50 м/мин, а оса - 150м/мин, ответь на следующие вопросы. 1) Когда вылетела оса, расстояние между шмелем и осой было 200м. Через сколько минут оса догонит шмеля? 2) Через сколько минут оса догонит шмеля, если расстояние между ними будет 600 метров? 3) На каком расстоянии от поля оса догонит шмеля, если он вылетит с поля на 5 минут раньше осы?

Answer 1

1)

1)150-50=100(м/мин)-скорость сближения шмеля и осы.

2)200:100=2(мин)

2)6 минут

3)5*50=250метров    

Answer 2

150-50=100 200:100=2 6минут 5*50=250

Answer 3

Question 1: Когда вылетела оса, расстояние между шмелем и осой было 200 м. Через сколько минут оса догонит шмеля?

To find out how long it will take for the wasp to catch up with the bumblebee, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the difference in speed between the wasp and the bumblebee.

Given that the bumblebee flies at a speed of 50 m/min and the wasp flies at a speed of 150 m/min, the relative speed is:

Relative Speed = Wasp's Speed - Bumblebee's Speed = 150 m/min - 50 m/min = 100 m/min

The initial distance between the wasp and the bumblebee is 200 m.

Time = Distance / Relative Speed = 200 m / 100 m/min = 2 minutes

Therefore, it will take the wasp 2 minutes to catch up with the bumblebee when the initial distance is 200 m.

Question 2: Через сколько минут оса догонит шмеля, если расстояние между ними будет 600 метров?

Using the same formula as in Question 1, we can calculate the time it will take for the wasp to catch up with the bumblebee when the distance between them is 600 meters.

Relative Speed = Wasp's Speed - Bumblebee's Speed = 150 m/min - 50 m/min = 100 m/min

The distance between the wasp and the bumblebee is 600 meters.

Time = Distance / Relative Speed = 600 m / 100 m/min = 6 minutes

Therefore, it will take the wasp 6 minutes to catch up with the bumblebee when the distance between them is 600 meters.

Question 3: На каком расстоянии от поля оса догонит шмеля, если он вылетит с поля на 5 минут раньше осы?

To determine the distance at which the wasp will catch up with the bumblebee when it takes off from the field 5 minutes earlier than the wasp, we need to calculate the distance traveled by each insect during that time.

The bumblebee flies at a speed of 50 m/min, so in 5 minutes, it will cover a distance of:

Distance = Speed x Time = 50 m/min x 5 min = 250 meters

The wasp flies at a speed of 150 m/min, so in 5 minutes, it will cover a distance of:

Distance = Speed x Time = 150 m/min x 5 min = 750 meters

Since the wasp takes off 5 minutes later, the initial distance between them will be:

Initial Distance = Distance traveled by the wasp - Distance traveled by the bumblebee = 750 meters - 250 meters = 500 meters

Using the formula from Question 1, we can calculate the time it will take for the wasp to catch up with the bumblebee when the initial distance is 500 meters.

Relative Speed = Wasp's Speed - Bumblebee's Speed = 150 m/min - 50 m/min = 100 m/min

Time = Distance / Relative Speed = 500 m / 100 m/min = 5 minutes

Therefore, the wasp will catch up with the bumblebee when it is 500 meters away from the field if it takes off 5 minutes earlier than the wasp.
