Question

Машина ехала до остановки 4 ч со скоростью 74 км/ч. после этого ей осталось проехать в 2 раза меньшее расстояние на которое ей понадобилось 2ч с какой скоростью ехала машина после остоновки

Answer 1

74*4=296 296/2= 148 148/2=74км/ч

Answer 2

Calculation of Speed after Stopping

To calculate the speed at which the car was traveling after stopping, we can use the information provided.

The car traveled for 4 hours at a speed of 74 km/h before stopping. After stopping, it had to travel a distance that was half the distance it had already traveled, and it took 2 hours to cover this distance.

Let's break down the problem step by step:

1. The car traveled for 4 hours at a speed of 74 km/h, covering a distance of 4 * 74 = 296 km. 2. After stopping, the car had to travel half the distance it had already traveled, which is 296 km / 2 = 148 km. 3. It took the car 2 hours to cover this distance, so the speed at which the car was traveling after stopping can be calculated as 148 km / 2 hours = 74 km/h.

Therefore, the car was traveling at a speed of 74 km/h after stopping
