Fig. 1.1 shows the thinking distance and the braking distance for a car being driven along a dry road and along a wet road at the same speed. [Figure 1.1 (table with thinking distance and braking distance for dry road and wet road)] thinking distance braking distance dry road 18 m 43 m wet road 18 m 60 m
