连接:在雨中驾驶

You are driving on the interstate, keeping up with the speed of traffic. Suddenly, you are hit with torrential rains. You cannot feel the road beneath your tires anymore. You cannot steer. Your brakes are not working as they normally do. What just happened?
::你开车在州际公路上, 跟上交通速度。 突然, 你被暴雨击中。 你再也感觉不到轮胎下面的路了。 你无法驾驶。 你的刹车没有正常工作。 刚刚发生了什么?

You are hydroplaning. When a car hydroplanes, it drives on top of a layer of water. Since it has lost contact with the roadway, it cannot easily change direction or stop.  Hydroplaning usually occurs at high speeds on roads with deep puddles. 
::您正在水力规划中。 当汽车水力规划中, 它会驾驶在水层之上。 由于它已经失去与公路的接触, 它无法轻易改变方向或停止。 水力规划通常会以高速在有深水坑的公路上进行。

Engineers have determined a formula that predicts when hydroplaning will occur: $\begin{array}{r}v=10.35\sqrt{p}\end{array}$ , where $\begin{array}{r}v\end{array}$  is the speed (in miles per hour) at which a car will hydroplane, and $\begin{array}{r}p\end{array}$  is the tire pressure (in PSI). This means that cars with underinflated tires are more likely to hydroplane. 
::工程师们已经确定了一个预测水力规划何时发生的公式:v=10.35p,其中车速(每小时英里)与车速(车速)之比,而p是轮胎压力(PSI ) 。 这意味着充气轮胎不足的汽车更有可能发生水力规划。

1. Mike is driving a Toyota Camry. He's inflated his tires to the dealer-recommended level of 32 PSI. At what speed will Mike's car start hydroplaning?
::1. 迈克驾驶丰田卡姆里,他将轮胎膨胀到经销商推荐的32 PSI水平。

2. With what tire pressure would his car start hydroplaning at 45 miles per hour?
::2. 他的汽车如果以每小时45英里的速度开始水力规划,其轮胎压力会有多大?

3. At 55 miles per hour? 
::3,每小时55英里?

4. At 65 miles per hour? 
::4. 每小时65英里?

5. Say Mike does not fill his tires with air for awhile and the tire pressure decreases to 30 PSI. At what speed will Mike's car start hydroplaning? 
::5. 说迈克有一阵子不给轮胎充气,轮胎压力降至30 PSI。 迈克的汽车以什么速度开始水力规划?

6. What about 28 PSI? 
::6. 28个防扩散安全倡议怎么办?

7. What transformation of the square root function comes from the constant 10.35? 
::7. 平方根函数的什么变化来自常数10.35?

8. Graph the function. What trends can you see in your graph? 
::8. 绘制函数图。您可以在图表中看到什么趋势?

by Defensive Driving explains the dangers of driving in the rain, the causes of hydroplaning, and how to avoid hydroplaning in different vehicle types.
