Question

1. Моторная лодка догоняет плот. Сейчас расстояние между ними 35 км. Скорость плота 3 км/ч, скорость лодки 10 км/ч. Через какое время моторная лодка догонит плот?

Answer 1

Ответ:

Пошаговое объяснение:

1) 3×5=15 (км) проплывет плот через 5 часов

2)10×5=50 (км) проплывет лодка через 5 часов

3) 35+15=50 (км)

В этом случае лодка догонит плот и они сравняются

Answer 2

Problem Analysis

We are given the following information: - The distance between a motorboat and a raft is currently 35 km. - The speed of the raft is 3 km/h. - The speed of the motorboat is 10 km/h.

We need to determine how long it will take for the motorboat to catch up to the raft.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it will take for the motorboat to catch up to the raft.

1. Calculate the time it will take for the raft to travel the given distance: - Distance = 35 km - Speed of the raft = 3 km/h - Time = Distance / Speed = 35 km / 3 km/h = 11.67 hours

2. Calculate the time it will take for the motorboat to travel the same distance: - Speed of the motorboat = 10 km/h - Time = Distance / Speed = 35 km / 10 km/h = 3.5 hours

Since the motorboat is faster than the raft, it will take less time for the motorboat to catch up to the raft. Therefore, the motorboat will catch up to the raft in approximately 3.5 hours.

Answer

The motorboat will catch up to the raft in approximately 3.5 hours.
