Speed, distance & stopping distance

At night on the N36 near Vriezenveen you are driving 100 km/h. What is your reaction distance per the book's rule of thumb?

Explanation

Wrong — trap: confusing seconds with metres. '1 second' is the reaction second (time); the reaction distance (metres) is ((100:2)+10%):2 = 27.50 m (Book p.125).
