Question

Автомобіль проїхав спочатку 100м за 5с, потім 200м він їхав зі швидкістю 36 км/год ,а потім 4 с їхав зі швидкістю 54 км/год . Який шлях подолав автомобіль ?

Answer 1

S = V*t
S = 54*4 = 216(метрів)
Всього автомобіль проїхав 100+200+216 = 516 (метрів)

Answer 2

Calculation of the Total Distance Traveled by the Car

To calculate the total distance traveled by the car, we need to add up the distances covered during each segment of the journey.

1. The car initially traveled 100 meters in 5 seconds. 2. Then, it traveled an additional 200 meters at a speed of 36 km/h. 3. Finally, it traveled for 4 seconds at a speed of 54 km/h.

Let's calculate the total distance traveled step by step:

1. Distance covered in the first segment: 100 meters. 2. Distance covered in the second segment: 200 meters. 3. Distance covered in the third segment: To calculate this, we need to convert the speed from km/h to m/s. Since 1 km/h is equal to 0.2778 m/s, the speed of 54 km/h is equal to 54 * 0.2778 = 15 m/s. Therefore, the distance covered in the third segment is 15 m/s * 4 s = 60 meters.

Now, let's add up the distances covered in each segment to find the total distance traveled by the car:

100 meters + 200 meters + 60 meters = 360 meters.

Therefore, the car traveled a total distance of 360 meters.
