Calculation of the Own Speed of the Boat and the Speed of the River

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

Own speed of the boat = (distance traveled downstream) / (time taken downstream) Speed of the river = (distance traveled upstream) / (time taken upstream)

Given the following information: - The boat traveled downstream for 3 hours and covered a distance of 114 km. - The boat traveled upstream for 2 hours and covered a distance of 64 km.

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

Own speed of the boat: The boat traveled downstream for 3 hours and covered a distance of 114 km. Therefore, the own speed of the boat is 114 km / 3 hours = 38 km/h.

Speed of the river: The boat traveled upstream for 2 hours and covered a distance of 64 km. Therefore, the speed of the river is 64 km / 2 hours = 32 km/h.

So, the own speed of the boat is 38 km/h and the speed of the river is 32 km/h.
