Question

Теплоход плыл 1,8 ч против течения реки и 2,6 ч по течению. Какой путь преодолел теплоход за всё время движения, если скорость течения равна 2,5 км/ч, а собственная скорость теплохода – 35,5 км/ч?

Answer 1

151,7км против-59,4км по-92,3 км

Answer 2

Calculation of the Distance Traveled by the Boat

To calculate the distance traveled by the boat, we need to consider the time it spent traveling against the current and the time it spent traveling with the current.

Given: - Time spent traveling against the current: 1.8 hours - Time spent traveling with the current: 2.6 hours - Speed of the current: 2.5 km/h - Speed of the boat: 35.5 km/h

To calculate the distance traveled against the current, we can use the formula: distance = speed × time. Using this formula, the distance traveled against the current is: 1.8 hours × (35.5 km/h - 2.5 km/h) = 60.6 km.

To calculate the distance traveled with the current, we can use the same formula. Using this formula, the distance traveled with the current is: 2.6 hours × (35.5 km/h + 2.5 km/h) = 101.4 km.

Therefore, the total distance traveled by the boat during the entire journey is the sum of the distances traveled against the current and with the current: 60.6 km + 101.4 km = 162 km.

So, the boat traveled a total distance of 162 kilometers during its entire journey.
