Answer 1

Ответ:

Vуд.= 30+35=65(км/ч)

Через 1час 65×1=66км

Problem Analysis

Two boats are leaving a dock simultaneously in opposite directions. The first boat has a speed of 30 km/h, and the second boat has a speed of 35 km/h. We need to determine the distance between the two boats after 1 hour and after 2 hours.

Solution

To find the distance between the two boats after a given time, we can use the formula:

Distance = Speed * Time

Let's calculate the distances after 1 hour and after 2 hours for each boat.

1. Distance after 1 hour: - Boat 1: Distance = 30 km/h * 1 hour = 30 km - Boat 2: Distance = 35 km/h * 1 hour = 35 km

2. Distance after 2 hours: - Boat 1: Distance = 30 km/h * 2 hours = 60 km - Boat 2: Distance = 35 km/h * 2 hours = 70 km

Therefore, after 1 hour, the two boats will be 30 km apart, and after 2 hours, they will be 60 km apart.

Note: The distances calculated above assume that the boats are moving in a straight line and at a constant speed.

Answer

The two boats will be: - 30 km apart after 1 hour. - 60 km apart after 2 hours.
