Texas Drivers Ed Written Practice Test

Explanation While all of these speeds are relatively slow, the important factor to consider in this situation is the distance you need to stop. At 15 mph, you would need approximately 27-30 feet to come to a complete stop, which is significantly less than the distance the child is currently at (60-65 feet). At 20 mph, you would need approximately 41-46 feet to stop, which gives you a better chance of avoiding hitting the child. At 25 and 30 mph, you would need even more distance to stop, making B the maximum speed you could travel and still have a reasonable chance of stopping before hitting the child. Therefore, options A, C, and D are incorrect as they would not provide enough time and distance for a timely and safe stop.
