One car length for every 10 mph.
A good rule of thumb is to keep a distance of one car length, about 10 feet, for every 10 mph of speed, so at 40 mph, you should be 40 feet behind the car in front of you. Obviously, this is harder to do in heavy traffic.
One car length for every 10 mph.
This refers to following distances, and the rule of thumb is one car length for every 10 MPH of speed. 50 MPH = 5 car lengths, but these days you're more likely to find five cars in there...
The rule of thumb is to maintain on car length for each ten miles of speed. Sixty five MPH would require a separation of 6.5 times one car length, of six and one half car lengths.
One car length for every 10 miles per hour of speed. If you are then traveling at 50 mph, one should allow at least 5 car lengths between you and the car in front of you.
160 mph falling out of a plane, 50 mph from a slingshot. Depending on the length and slope of your track from less than 1 mph to 160+
That depends on vehicle speed. At 60 mph a vehicle covers 88 feet in one second. It also depends on the length of the car, but assuming the average car is 15 feet in length, it takes less than 2 tenths of a second to travel one "car length" at 60 mph. So in one second, the average car covers almost 6 car lengths! Double the speed - 120 mph - and that same car covers 176 feet in one second; more than half the length of a football field.
