Question

Помогите решить задачу: Теплоход проходит за 4 часа, такое же расстояние протходит моторная лодка за 9 часов. Узнай расстояние моторной лодки если скорость теплохода 36 км в час?

Answer 1

Расстояние, которое прошли теплоход и лодка 36 км/час * 4 часа = 144 км.
Средняя скорость лодки 144 км : 9 час = 16 км/час.

Answer 2

Problem Analysis

To solve this problem, we can use the formula: distance = speed × time. We are given the speed of the steamboat (36 km/h) and the time it takes to cover a certain distance (4 hours). We need to find the distance covered by the motorboat in 9 hours.

Solution

Let's calculate the distance covered by the steamboat using the given information: distance = speed × time distance = 36 km/h × 4 hours distance = 144 km

Now, we can use the distance covered by the steamboat to find the speed of the motorboat. We know that the motorboat covers the same distance in 9 hours. Let's use the formula again: speed = distance / time speed = 144 km / 9 hours speed = 16 km/h

Therefore, the speed of the motorboat is 16 km/h.

Now, we can find the distance covered by the motorboat using its speed and the given time: distance = speed × time distance = 16 km/h × 9 hours distance = 144 km

Therefore, the distance covered by the motorboat is 144 km.

Answer

The distance covered by the motorboat is 144 km.
