Question

Власна швидкість катера 19,8км\год,а швидкість течії річки 2,1 км\год . Яку відстань подолає катер, рухаючись 3 год за течією річки?

Answer 1

19,8 + 2,1 = 21,9 км/ч - скорость по течению

21,9 * 3 = 65,7 км - пройдет катер по течению за 3 часа

Answer 2

Calculation of Distance Traveled by the Boat

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

Distance = Speed × Time

Given that the boat's speed is 19.8 km/h and it moves for 3 hours with the river's current, we can calculate the distance traveled as follows:

Distance = (Boat's Speed + River's Current) × Time

Substituting the given values:

Distance = (19.8 km/h + 2.1 km/h) × 3 hours

Calculating the sum:

Distance = 22.9 km/h × 3 hours

Simplifying the equation:

Distance = 68.7 km

Therefore, the boat will travel a distance of 68.7 kilometers while moving with the river's current for 3 hours.
