Question

Теплоход 3 часа шел по озеру со скоростью 23 км в час а потом 4 часа по реке сколько километров прошел теплоход за эти 7 часов если по реке он шел на 3 километров час быстрее чем по озеру

Answer 1

3×23=69км прошел по озеру
23+3=26км/ч по реке
4×26=104 км прошел по реке
69+104=173 км прошел всег

Answer 2

Calculation of Distance Traveled by the Boat

To calculate the distance traveled by the boat, we need to determine the distance covered on the lake and the distance covered on the river separately.

Let's assume that the boat traveled at a speed of 23 km/h on the lake and at a speed of (23 + 3) km/h on the river.

The boat traveled on the lake for 3 hours and on the river for 4 hours.

To calculate the distance traveled on the lake, we can use the formula: distance = speed × time.

So, the distance traveled on the lake is: 23 km/h × 3 hours = 69 km.

To calculate the distance traveled on the river, we can use the same formula: distance = speed × time.

So, the distance traveled on the river is: 26 km/h × 4 hours = 104 km.

Therefore, the total distance traveled by the boat in these 7 hours is: 69 km + 104 km = 173 km.

Answer:

The boat traveled a total distance of 173 kilometers in these 7 hours, covering 69 kilometers on the lake and 104 kilometers on the river.
