Question

Как решить задачу:Путешествуя ото Углича по Волге на катере,ребята в первый день проплыли 72 км,А во второй день с той же скоростью-48 км.Сколько всего часов длилась экскурсия на катере,если во второй день катер был в пути на два часа меньше,чем в первый?(решить по действиям)

Answer 1

Мне лень писать
ответ:10часов длилась экскурсия

Answer 2

72-48=24км плыли2  часа
24/2=12 км/ч скорость катера
72/12=6часов плыли в первый день
48/12=4 часа плыли во второй день( на 2часа меньше)
6+4=10 часов длилась экскурсия.

Answer 3

Problem Analysis

To solve this problem, we need to determine the total duration of the boat excursion based on the distances traveled on the first and second days, as well as the difference in time spent on the second day compared to the first day.

Solution Steps

1. Calculate the time taken to travel 72 km on the first day. 2. Calculate the time taken to travel 48 km on the second day. 3. Determine the difference in time between the first and second days. 4. Subtract the time difference from the total duration of the excursion on the first day to find the total duration of the excursion.

Solution

1. Calculate the time taken to travel 72 km on the first day: - We can use the formula: time = distance / speed. - Let's assume the speed of the boat is constant. - Since the distance traveled on the first day is 72 km, we can calculate the time taken: time1 = 72 km / speed.

2. Calculate the time taken to travel 48 km on the second day: - Using the same formula, we can calculate the time taken on the second day: time2 = 48 km / speed.

3. Determine the difference in time between the first and second days: - We are given that the boat was in motion for 2 hours less on the second day compared to the first day. - Therefore
