Question

Скорость течения 2,2 км/ч. Собственная скорость катера 15,3 км/ч. Какой путь прошел катер, если по течению он шел 3ч, если скорость течения 4,5 км/ч?

Answer 1

1) 15,3 + 2,2 = 17,5 км/ч - скорость по течению

2) 15,3 - 2,2 = 13,1 км/ч - скорость против течения

3) 17,5 * 3 + 13,1 * 4 = 52,5 + 52,4 = 104,9 км

Answer 2

Если скорость течения 4.5 км/ч,то...

Скорость по течению=4.5+15.3=19.8км/ч

Путь(S)= 19.8*3=59.4 км.

А если скорость течения 2.2 км/ч,то просто 4.5 замени 2.2)) А то не очень понятно)

Answer 3

Calculation of the Distance Traveled by the Boat

To calculate the distance traveled by the boat, we need to consider the speed of the current and the speed of the boat.

Given: - Speed of the current: 2.2 km/h - Speed of the boat: 15.3 km/h - Time traveled with the current: 3 hours - Speed of the current in the second scenario: 4.5 km/h

To calculate the distance traveled by the boat in each scenario, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by the boat in each scenario.

1. When the boat is traveling with a current speed of 2.2 km/h for 3 hours:

Distance = (Speed of the boat + Speed of the current) × Time

Distance = (15.3 km/h + 2.2 km/h) × 3 hours

Distance = 17.5 km/h × 3 hours

Distance = 52.5 km

2. When the boat is traveling with a current speed of 4.5 km/h:

Distance = (Speed of the boat + Speed of the current) × Time

Distance = (15.3 km/h + 4.5 km/h) × 3 hours

Distance = 19.8 km/h × 3 hours

Distance = 59.4 km

Therefore, the boat traveled a distance of 52.5 km when the current speed was 2.2 km/h, and a distance of 59.4 km when the current speed was 4.5 km/h.
