Средняя скорость 75 км/час если считать 2 часа езды
если посчитать 3 часа то будет 50 км/час 
среднюю скорость вычеслил так:
1)60+90=150
2)150:2=75 (или)150:3=50

Answer 2

Calculation of the Car's Speed

To calculate the speed of the car, we need to determine the total distance traveled and the total time taken.

Given the information provided, the car traveled 60 km in the first hour, then stood still for 1 hour, and finally traveled an additional 90 km in the third hour.

To find the total distance traveled, we add the distances covered in each hour: 60 km + 90 km = 150 km.

To find the total time taken, we add the time spent in each hour: 1 hour + 1 hour + 1 hour = 3 hours.

Now, we can calculate the speed of the car by dividing the total distance traveled by the total time taken:

Speed = Total Distance / Total Time

Speed = 150 km / 3 hours

Speed = 50 km/h

Therefore, the speed of the car is 50 km/h.
