Question

Катер, собственная скорость которого 14,8 км/ч, шел 3ч по течению и 4ч против течения. Какой путь проделал катер за все время, если скорость течения 2,3 км/ч

Answer 1

1)14,8+2,3=17,1(км/ч)-скорость по течению

2)17,1х3=51,3(км)-прошёл катер по течению за 3 ч

3)14,8-2,3=12,5(км/ч)-скорость против течения

4)12,5х4=50(км)-проехал катер против течения за 4 ч

Вроде так.

:)

Answer 2

1) 14,8+2,3=17,1 (км/ч) - скорость по т.р. 

2) 14,8-2,3=12,5(км/ч) - скорость против т.р. 

3) 17,1х3=51,3(км) - по т.р. 

4) 12,5х4=50(км) - против т.р. 

Ответ: По течению реки катер прошёл 51,3 км, против течения реки 50 км.

Answer 3

Calculating the Distance Traveled by the Boat

To calculate the distance traveled by the boat, we can use the formula: distance = speed × time

First, let's calculate the distance traveled by the boat when going with the current: - Speed of the boat = 14.8 km/h - Speed of the current = 2.3 km/h - Time spent going with the current = 3 hours

Using the formula, the distance traveled with the current is: distance = (boat's speed + current's speed) × time distance = (14.8 + 2.3) × 3 = 51.3 km Next, let's calculate the distance traveled by the boat when going against the current: - Speed of the boat = 14.8 km/h - Speed of the current = 2.3 km/h - Time spent going against the current = 4 hours

Using the formula, the distance traveled against the current is: distance = (boat's speed - current's speed) × time distance = (14.8 - 2.3) × 4 = 50 km Now, we can calculate the total distance traveled by the boat: Total distance = distance with the current + distance against the current Total distance = 51.3 km + 50 km = 101.3 km

So, the boat traveled a total distance of 101.3 kilometers.
