Answer 1

3*53.5=160.5- путь за 3 часа
2*62.3=124.6- путь за 2часа

Answer 2

Problem Statement

We are given the following information about a car's journey: - The car traveled for 3 hours at a speed of 53.5 km/h. - The car then traveled for 2 hours at a speed of 62.3 km/h. - Finally, the car traveled for 4 hours at a speed of 48.2 km/h.

We need to find the average speed of the car for the entire journey.

Solution

To find the average speed, we can use the formula:

Average Speed = Total Distance / Total Time

To calculate the total distance, we need to find the distance traveled during each leg of the journey and then sum them up.

Let's calculate the distance traveled during each leg of the journey:

- Distance traveled during the first leg (3 hours at 53.5 km/h): - Distance = Speed x Time = 53.5 km/h x 3 hours = 160.
