Question

Велосипед ехавший на со скоростью 219,2 м/мин решил догнать своего друга который шел пешком скорость друга была в 3,2 раза меньше скорости велосипедиста а растояние между ними 452,1 м через какое время велосипедист дагонит друга

Answer 1

1) 219,2/ 3,2=68,5 м/мин - скорость друга2) 219,2-68,5 = 150,7 м/мин - скорость сближения3) 452,1 : 150,7 = 3 минуты    - через 3 минуты догонитОтвет: 3 минуты.

Answer 2

Calculating the Time for the Cyclist to Catch Up to the Pedestrian

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

Time = Distance / Relative Speed

Where: - Distance is the initial distance between the cyclist and the pedestrian. - Relative Speed is the difference in speed between the cyclist and the pedestrian.

Given Information

- Speed of the cyclist = 219.2 m/min - Speed of the pedestrian = 3.2 times less than the speed of the cyclist - Distance between them = 452.1 m

Calculating Relative Speed

The relative speed is the difference between the speeds of the cyclist and the pedestrian.

The speed of the pedestrian can be calculated as: Pedestrian's speed = Cyclist's speed / 3.2

Relative Speed = Cyclist's speed - Pedestrian's speed

Calculating Time

Using the formula mentioned earlier, we can calculate the time it takes for the cyclist to catch up to the pedestrian.

Time = Distance / Relative Speed

Substitute the given values: Time = 452.1 / (219.2 - (219.2 / 3.2))

Now, let's calculate the time.
