Question

Два катера отплыли одновременно от пристани в одном направлении. Скорость одного из них 35 км/ч,а у другого 25 км/ч. Какое расстояние будет между ними через 1,5ч? Помогите, пожалуйста. После каникул ничего не помню. По действиям, пожалуйста!

Answer 1

35-25=10 км/ч скорость удаления.
10×1,5=15 км будет между ними через 1,5 часа.
Ответ: 15 км.

Answer 2

1) 35-25=10 км/ч -скорость удаления
2) 10·1,5=15 км - расстояние между двумя катерами через 1,5ч

Answer 3

Problem Analysis

Two boats depart simultaneously from a dock in the same direction. The speed of one boat is 35 km/h, and the speed of the other boat is 25 km/h. We need to calculate the distance between them after 1.5 hours.

Solution

To find the distance between the two boats after 1.5 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance for each boat and then find the difference between them.

Boat 1: - Speed: 35 km/h - Time: 1.5 hours - Distance = 35 km/h × 1.5 hours = 52.5 km

Boat 2: - Speed: 25 km/h - Time: 1.5 hours - Distance = 25 km/h × 1.5 hours = 37.5 km

The distance between the two boats after 1.5 hours is the difference between their distances:

Distance between the boats = Distance of Boat 1 - Distance of Boat 2 = 52.5 km - 37.5 km = 15 km

Therefore, the distance between the two boats after 1.5 hours is 15 kilometers.

Answer

The distance between the two boats after 1.5 hours will be 15 kilometers.
