Answer 1

23*4=92 прошла 1 лодка 
180-92=88 прошла 2 лодка
88/4=22 скорость 2 лодки

Answer 2

Problem Analysis

We are given that two motorboats set off from opposite shores in opposite directions. The first boat has a speed of 23 km/h, and after 4 hours, the distance between the two boats is 180 km. We need to find the speed of the second boat.

Solution

Let's assume that the speed of the second boat is x km/h.

After 4 hours, the first boat has traveled a distance of 23 km/h * 4 h = 92 km.

The total distance between the two boats is 180 km, and the first boat has already traveled 92 km. Therefore, the second boat must have traveled 180 km - 92 km = 88 km in 4 hours.

To find the speed of the second boat, we can use the formula:

Speed = Distance / Time

The speed of the second boat is given by:

x = 88 km / 4 h = 22 km/h

Therefore, the speed of the second boat is 22 km/h.

Answer

The speed of the second boat is 22 km/h.
