Velocity, in km/hr is the x-axis. Breaking distance "s" in meters is on the y-axis. Each curved line represents the different road conditions.
for (a.) find the y-coordinate for each Dry, curve A. follow the 50km/hr up to the curve and see it corresponds to about 30 m Wet road, curve B. follow the 50km/hr mark up to see it corresponds to 80 m Icey, curve T is 140 m
for (b.) they give you the breaking distance on the y-axis to find the corresponding speeds for each road condition. Follow the 60 m mark across to find each x-coordinate,. Dry curve A, 70 km/hr Wet curve B, about 45 km/hr Icey curve T, 30 km/hr
