Question

Легковой автомобиль,движущийся со скоростью U1=108 км/ч, движется на встречу грузовику, который имей скорость U1=20 м/с. Каким будет расстояние между автомобилями через ∆t=5 мин. после их встречи?​

Answer 1

V1=108км/ч
V2=20км/час
t=5мин
S-? S=(v1+v2)*t=(108+20)/5=25,6м

Answer 2

To find the distance between the car and the truck after their encounter, we can use the formula:

Distance = (Relative Speed) x (Time)

First, let's convert the speeds to the same unit. The car's speed is given as 108 km/h, and the truck's speed is given as 20 m/s.

Converting the car's speed from km/h to m/s: U1 = 108 km/h = (108 x 1000) m/3600 s = 30 m/s

Now we can calculate the relative speed: Relative Speed = U1 + U2 = 30 m/s + 20 m/s = 50 m/s

Next, we need to convert the time from minutes to seconds. The given time is 5 minutes, which is equal to 5 x 60 = 300 seconds.

Finally, we can calculate the distance using the formula: Distance = Relative Speed x Time = 50 m/s x 300 s = 15000 meters

Therefore, the distance between the car and the truck after 5 minutes will be 15000 meters.
