Question

Теплоход ракета идет по реке со скоростью 55 километров в час. Впереди теплохода идет баржа со скоростью 25 км в час. Какое расстояние будет между ними через 3 часа, если сейчас баржа впереди теплохода на 50 километров

Answer 1

55 - 25 = 30 - скорость с которой догоняет
30 умножить на 3 = 90
90 - 50 = 40 - теплоход ракета впереди на 40 ки

Answer 2

Calculation of the Distance Between the Rocket Boat and the Barge

To calculate the distance between the rocket boat and the barge after 3 hours, we need to consider their respective speeds and the initial distance between them.

Given: - Speed of the rocket boat: 55 km/h - Speed of the barge: 25 km/h - Initial distance between the barge and the rocket boat: 50 km

To find the distance between them after 3 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by the rocket boat and the barge separately after 3 hours:

- Distance traveled by the rocket boat: 55 km/h × 3 h = 165 km - Distance traveled by the barge: 25 km/h × 3 h = 75 km

Now, let's calculate the final distance between the rocket boat and the barge:

- Final distance = Initial distance + Distance traveled by the rocket boat - Distance traveled by the barge - Final distance = 50 km + 165 km - 75 km = 140 km

Therefore, after 3 hours, the distance between the rocket boat and the barge will be 140 kilometers.
