Question

Автомобиль "Рено" проезжает за 1 мин. путь 1,2 км. Автомобиль "Пежо" проезжает за 20 сек. путь 0,2 км. Нужно найти V1 (скорость "Рено") и V2 (скорость "Пежо") в м/с

Answer 1

Ответ:

V1 = 72 км/ч, V2 = 36 км/ч

Объяснение:

Если за 1 минуту - 1,2 км, то за 60 минут - x км, следовательно

V1 = 60* 1,2 = 72 км/ч

Если за 20 сек - 0,2 км, то за 3600 сек - х км, следовательно

V2 = (3600*0,2)/20 = 36 км/ч

Answer 2

Given Information:

- The Renault car travels a distance of 1.2 km in 1 minute. - The Peugeot car travels a distance of 0.2 km in 20 seconds.

Calculating Speed:

To find the speed of each car, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the Renault car (V1) first: - Distance = 1.2 km - Time = 1 minute = 60 seconds

V1 = 1.2 km / 60 seconds

Now, let's calculate the speed of the Peugeot car (V2): - Distance = 0.2 km - Time = 20 seconds

V2 = 0.2 km / 20 seconds

Converting Speed to m/s:

The speeds we calculated are currently in km/second. To convert them to m/s, we need to multiply by 1000 (since there are 1000 meters in a kilometer).

V1 = (1.2 km / 60 seconds) * 1000 = 20 m/s

V2 = (0.2 km / 20 seconds) * 1000 = 10 m/s

Therefore, the speed of the Renault car (V1) is 20 m/s and the speed of the Peugeot car (V2) is 10 m/s.
