Answer 1

1) 10+8= 18(км\ч)-общая скорость.
2)90:18=5(ч) - Время
Ответ:через 5 часов

Answer 2

Calculating the Meeting Time of Boats

To calculate the time it takes for the two boats to meet, we can use the formula: time = distance / (speed1 + speed2)

Given: - Distance between the two boats = 90 km - Speed of the first boat = 8 km/h - Speed of the second boat = 10 km/h

Using the formula, we can calculate the time it takes for the two boats to meet.

time = 90 / (8 + 10) time = 90 / 18 time = 5 hours

Therefore, the two boats will meet after 5 hours.
