pass others on the left
You should get a sufficintly accurate indication after 10 seconds and, that way, you save a whole 50 seconds!
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.
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.
10-15 feet . You need to be 2 full seconds behind. Pick stationary object vehicle in front passes, then count how long until you pass the same object. Not 2 seconds? Increase you following distance! Another rule of thumb is to stay behind one car length for every 10 miles per hour, so at 35 mph you would want to be 3 and 1/2 cars behind the car in front of you.

It is five seconds
I usually leave 5 to 6 seconds minimum following distance under those condition, and have had no accidents . . .
If it is raining and you are tired, you probably should not be driving - you are a hazard to yourself and other drivers when you drive in those conditions. However, if you must drive, keep a solid 10 to 15 seconds of following distance between you and the next car on the road.

When driving, you should always measure your following distance in seconds. A general rule of thumb is to maintain a following distance of at least 3-4 seconds between your vehicle and the one in front of you. This distance allows you enough time to react and brake safely in case of an emergency.

Several hundred. You should stop and rest.

4 to 5 seconds
Following distance is typically measured in seconds. A common rule of thumb is the "3-second rule" where you should leave at least 3 seconds of following distance between your vehicle and the vehicle in front of you. To measure this, pick a stationary object on the side of the road, wait for the vehicle ahead of you to pass it, and then count how many seconds it takes for you to pass the same object.
