This is why it is important to leave a safe following distance between you and the car in front of you, so that you have enough time and space to brake in time if necessary. a lower RHR indicates more efficient heart function, though RHRs that are lower than 50 bpm can be a sign of an underlying heart condition or disease. For example, cars equipped with budget tyres can take an extra 14 metres to stop from 70mph in wet conditions compared to cars with premium brand tyres, or five metres in the dry. 2 x 3 = 6. Clearly, it's different than the typical formula used in the speed calculator. 60mph x 4 = 240 feet. . It is equal to exactly 1.609344 kilometers per hour. On a dry road the stopping distances are the following: On a wet road the stopping distances are the following: The answer is a bit less than 50 m. To get this result: Moreover, we assume an average perception-reaction time of 2.5 seconds. It is most widely used in the United States, the United Kingdom, and their related territories. The braking distance at 70mph is a huge 75m, which is about 9 London buses. Because the distance D varies directly with the square of the speed R, we can come up with the equation D=kR 2 where k is some constant. When it comes to braking, always follow these three key defensive driving principles: Keep your speed down. AASHTO recommends the value of 2.5 seconds to ensure that virtually every driver will manage to react within that time. For example, here's how to convert 5 miles per hour to feet per second using the formula above. Its not always as obvious as bad weather equals long stopping distances, either.
