Question

Теплоход за 2 часа проходит по течению реки56 км,а против течения 66 км за 3 часа Найти скорость течения реки и собственную скорость теплохода

Answer 1

56:2=28км/ч - скорость теплохода по течению
66:3 = 22км/ч - скорость теплохода против течения
(28+22):2=25км/ч- собственная скорость теплохода
28-25=3км/ч скорость реки

Answer 2

Calculation of River Current Speed and Boat's Speed

To find the speed of the river current and the speed of the boat, we can use the formula:

Boat's speed = (Distance traveled downstream) / (Time taken downstream)

River current speed = (Distance traveled upstream) / (Time taken upstream)

Given the following information:

- Distance traveled downstream = 56 km - Time taken downstream = 2 hours - Distance traveled upstream = 66 km - Time taken upstream = 3 hours

Let's calculate the speed of the river current and the speed of the boat.

Calculation:

Boat's speed = (Distance traveled downstream) / (Time taken downstream) = 56 km / 2 hours = 28 km/h.

River current speed = (Distance traveled upstream) / (Time taken upstream) = 66 km / 3 hours = 22 km/h.

Therefore, the speed of the river current is 22 km/h and the speed of the boat is 28 km/h.
