Question

Найдите скорость течения реки, если за 5 часов катер прошел по течению 96,5 км, а за 4,8 ч против течения – 81,6 км.

Answer 1

96,5: 5=19,3 км/ ч ( по течению)
81,6:4,8= 17 км/ч ( против теяения)
19,3 - 17= 2,3 (разница скорости)
2,3 : 2= 1,15 км/ч
Ответ: 1,15

Answer 2

Calculation of River Current Speed

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

Speed of the current = (Distance traveled downstream - Distance traveled upstream) / (Time taken downstream + Time taken upstream)

Given the following information: - Distance traveled downstream = 96.5 km - Time taken downstream = 5 hours - Distance traveled upstream = 81.6 km - Time taken upstream = 4.8 hours

Let's substitute these values into the formula to calculate the speed of the river current.

Speed of the current = (96.5 km - 81.6 km) / (5 hours + 4.8 hours)

Simplifying the equation:

Speed of the current = 14.9 km / 9.8 hours

Therefore, the speed of the river current is approximately 1.52 km/h.
