How many times will the braking distance lengthen if you double the speed of the bus that you are driving?

Explanation

Correct answer: Four times.

The braking distance is directly proportional to the square of the vehicle's speed. This means that doubling the speed results in a fourfold (2 squared) increase in the distance required to stop. This principle of physics is crucial for maintaining safety, especially when driving a heavy vehicle, such as the bus visible in the picture.
