Answer 1

Решение:
1) 48+42=90(км в час) плыл катер

Answer 2

Calculation of the Boat's Speed

To determine the speed at which the boat was traveling, we can use the formula: speed = distance / time.

Let's calculate the distance traveled during each leg of the journey and the time it took for each leg:

1. First leg: The boat traveled for 2 hours at a speed of 48 kilometers per hour. - Distance = speed * time = 48 km/h * 2 h = 96 km

2. Second leg: The boat traveled for 3 hours at a speed of 42 kilometers per hour. - Distance = speed * time = 42 km/h * 3 h = 126 km

Now, let's calculate the average speed of the boat for the entire journey:

- Total distance = distance of the first leg + distance of the second leg = 96 km + 126 km = 222 km - Total time = time of the first leg + time of the second leg = 2 h + 3 h = 5 h

- Average speed = total distance / total time = 222 km / 5 h = 44.4 km/h

Therefore, the boat was traveling at an average speed of 44.4 kilometers per hour during the entire journey.
