Question

1) Теплоход за 2 дня прошол 375км В первый день он был в пути 8ч, а в второй 7 ч. Какое расстояние он прошёл в каждый из дней, если шёл с одинаковой средней скоростью? 2) Теплоход за 2 дня был в пути 15ч. В первый день он прошёл 200км, а во второй 175км. Сколько часов теплоход был в пути каждый день, если шёл с одинаковой средней скоростью?

Answer 1

Ответ:

1) 200 км за 1-день

175 км за 2-день

2) 8 ч за 1-день

7 ч за 2-день

Пошаговое объяснение:

1) 8+7=15 ч -за 2 дня

375:15=25 км за час

8×25=200 км за 1-день

7×25=175 км за 2-день

2) 200+175=375 км за 2 дня

375:15=25 км за час

200:25=8 ч за 1-день

175÷25=7 ч за 2-день

Answer 2

Problem 1:

To find the distance traveled by the ship each day, we need to divide the total distance traveled by the number of days.

Given: - Total distance traveled: 375 km - Time spent on the first day: 8 hours - Time spent on the second day: 7 hours

To find the distance traveled on each day, we can use the formula:

Distance = Speed × Time

Since the ship traveled at the same average speed on both days, we can assume that the speed remains constant.

Let's calculate the distance traveled on each day:

1. Distance traveled on the first day: - Time spent: 8 hours - Distance = Speed × Time - Distance = Speed × 8

2. Distance traveled on the second day: - Time spent: 7 hours - Distance = Speed × Time - Distance = Speed × 7

Since the average speed remains the same, we can set the two distances equal to each other:

Speed × 8 = Speed × 7

Simplifying the equation, we get:

8 = 7

This equation is not possible, as 8 is not equal to 7. Therefore, there seems to be an error in the given information or calculations.

Unfortunately, without additional information or clarification, we cannot determine the exact distances traveled on each day.

Problem 2:

To find the time spent by the ship each day, we need to divide the total time spent by the number of days.

Given: - Total time spent: 15 hours - Distance traveled on the first day: 200 km - Distance traveled on the second day: 175 km

To find the time spent on each day, we can use the formula:

Time = Distance / Speed

Since the ship traveled at the same average speed on both days, we can assume that the speed remains constant.

Let's calculate the time spent on each day:

1. Time spent on the first day: - Distance traveled: 200 km - Time = Distance / Speed - Time = 200 / Speed

2. Time spent on the second day: - Distance traveled: 175 km - Time = Distance / Speed - Time = 175 / Speed

Since the average speed remains the same, we can set the two times equal to each other:

(200 / Speed) = (175 / Speed)

Simplifying the equation, we get:

200 = 175

This equation is not possible, as 200 is not equal to 175. Therefore, there seems to be an error in the given information or calculations.

Unfortunately, without additional information or clarification, we cannot determine the exact time spent on each day.

Please double-check the given information or provide any additional details to help us solve the problems accurately.
