Question

Answer 1

Ответ: На 10 км и 1 час.

Answer 2

Calculation of Speed

To calculate the speed of the train and the boat, we can use the formula:

Speed = Distance / Time

Given that the train traveled 90 km in 3 hours and the boat traveled 80 km in 4 hours, we can calculate their speeds as follows:

Train speed = 90 km / 3 hours = 30 km/h. Boat speed = 80 km / 4 hours = 20 km/h.

Difference in Speed

To find the difference in speed between the train and the boat, we subtract the boat's speed from the train's speed:

Difference in speed = Train speed - Boat speed = 30 km/h - 20 km/h = 10 km/h.

Therefore, the train is 10 km/h faster than the boat.
