If you are traveling at 55 miles per hour in a 30 foot vehicle you should leave how many seconds of following distance?
When traveling at 55 miles per hour, a good rule of thumb for following distance is to maintain at least one second of distance for every 10 feet of your vehicle's length. Since your vehicle is 30 feet long, you should leave approximately 3 seconds of following distance. This allows for adequate reaction time and helps ensure safety on the road.
When driving in the rain besides reducing your speed and increasing your following distance you should?
pass others on the left
Why should you measure your pulse over 10 seconds and not 60?
You should get a sufficintly accurate indication after 10 seconds and, that way, you save a whole 50 seconds!
If speed is a function of time or velocity is a function of time Then what should you do to calculate distance?
Distance equals speed multiplied by time. For example, speed is 72 km/h and time is 200 seconds or 200/3600=0,0(5) hours, so the distance traveled is 72*0,0(5)=4 kilometers.
Should you measure in feet seconds or car length when following?
Which ever you find easier. Find a fixed point ahead i.e. a telegraph pole. As the car in front passes it, in good driving conditions, say to yourself at normal speed, "Only a fool breaks the two second rule!" If you passed the pole before you finished it, you are too close to the vehicle in front. If you finished it way before you reached the pole, you are too far away from the vehicle in front. The two second rule mantra automatically adjusts the distance between vehicles dependent on speed. However, you must increase the distance by at least 50% for wet/slippy conditions. Repeating the first half of the phrase will do that.
