Question

От склада с новогодними подарками одновременно в противоположном направлении отъехали два грузовика. Первый со скоростью 45 км час , второй в два раза быстрее . Какой расстояние будет между ними через два часа ?

Answer 1

Второй едет со скоростью 90 км/ч: 45*2=90. Т.к. они едут в противоположных направлениях, то 90+45=135 км/ч. S=135*2=270км, по формуле

Answer 2

Calculation of the Distance Between the Two Trucks

To calculate the distance between the two trucks after two hours, we need to determine the distance each truck has traveled in that time.

Given that the first truck is traveling at a speed of 45 km/h, we can calculate its distance using the formula:

Distance = Speed × Time

For the first truck: Distance1 = 45 km/h × 2 h = 90 km

Now, let's calculate the speed of the second truck. It is stated that the second truck is traveling at twice the speed of the first truck. Therefore, the speed of the second truck is:

Speed2 = 2 × Speed1 = 2 × 45 km/h = 90 km/h

Using the same formula as before, we can calculate the distance traveled by the second truck:

Distance2 = 90 km/h × 2 h = 180 km

Therefore, after two hours, the first truck will have traveled 90 km, and the second truck will have traveled 180 km.

Calculation of the Distance Between the Two Trucks

The distance between the two trucks after two hours can be calculated by subtracting the distance traveled by the first truck from the distance traveled by the second truck:

Distance between the two trucks = Distance2 - Distance1

Substituting the values we calculated earlier:

Distance between the two trucks = 180 km - 90 km = 90 km

Therefore, the distance between the two trucks after two hours will be 90 kilometers.
