Question

В первый час теплоход прошел 24,5 км,во второй- на 7,5 км больше,чем впервый,а в третий - на 20,5 км меньше,чем вза первые два часа вместе.Найдите расстояние,которое прошёл теплоход за 3 часа.

Answer 1

1) 24,5+7,5= 32 (км) - во второй час.
2) 24,5+32= 56, 5 (км) - первые два часа.
3) 56,5-20,5= 36 (км) - в третий час.
4) 24,5+32+36= 92,5 (км) - за 3 часа.
Ответ: Теплоход прошёл за 3 часа 92,5 км

Answer 2

Calculation of Distance Traveled by the Ship

To find the distance traveled by the ship in 3 hours, we need to add up the distances covered in each hour.

Given: - In the first hour, the ship traveled 24.5 km. - In the second hour, the ship traveled 7.5 km more than in the first hour. - In the third hour, the ship traveled 20.5 km less than the combined distance covered in the first two hours.

Let's calculate the distance traveled in each hour and then sum them up to find the total distance traveled.

1. Distance traveled in the first hour: 24.5 km. 2. Distance traveled in the second hour: 7.5 km more than the first hour's distance, which is 24.5 + 7.5 = 32 km. 3. Distance traveled in the third hour: 20.5 km less than the combined distance covered in the first two hours, which is (24.5 + 32) - 20.5 = 36 km.

Therefore, the total distance traveled by the ship in 3 hours is 24.5 + 32 + 36 = 92.5 km.
