Stopping distance of a car traveling at 80mph?
The overall stopping distance would be around 122m (400ft)
This is made up of a thinking distance of 24m (79ft) and an
actual stopping distance of 98m (321ft).
The thinking distance is around 3m for every 10mph of speed and
the overall stopping distance is calculated as follows:
2x20 ft at 20mph
2.5x30 ft at 30mph
3x40 ft at 40mph
3.5x50 ft at 50mph
4x60 ft at 60mph
4.5x70 at 70mph
5x80 at 80mph = 400 ft james s
