Answer 2

Calculating the Boat's Distance Traveled Against the River Current

To calculate the distance the boat will travel against the river current, we can use the formula: distance = speed * time.

Given: - Boat's speed = 35 km/h - River's current speed = 5 km/h - Time = 4 hours

The boat's effective speed against the current can be calculated as the difference between the boat's speed and the river's current speed: 35 km/h - 5 km/h = 30 km/h.

Using the formula distance = speed * time, the distance the boat will travel against the river current is: distance = 30 km/h * 4 h = 120 km.

Therefore, the boat will travel a distance of 120 kilometers against the river current in 4 hours.
