Question

Грузовик едет со скоростью 75 км\ч,за ним легковой автомобиль со скоростью 90 км\ч. На каком расстоянии друг от друга они будут через 3 минуты после того,как легковой автомобиль догонит грузовой?

Answer 1

90-75=15км/час скорость удаления
3мин=1/20часа
15*1/20=0,75км через 3 минуты

Answer 2

Calculating the Distance Between Vehicles

To calculate the distance between the two vehicles after the car overtakes the truck, we can use the formula:

Distance = Relative Speed × Time

First, we need to find the relative speed of the car with respect to the truck.

Relative Speed Calculation

The relative speed of the car with respect to the truck is the difference between their speeds:

Relative Speed = Speed of Car - Speed of Truck

Given: - Speed of Car = 90 km/h - Speed of Truck = 75 km/h

Relative Speed = 90 km/h - 75 km/h = 15 km/h

Converting Time

The time given is 3 minutes, which needs to be converted to hours for consistency:

3 minutes = 3/60 hours = 0.05 hours

Calculating the Distance

Now, we can use the formula to find the distance between the car and the truck after 3 minutes:

Distance = Relative Speed × Time

Distance = 15 km/h × 0.05 hours = 0.75 km

Therefore, the car will be 0.75 kilometers away from the truck after 3 minutes.
