Question

PLEASE HELP ASAP:))) I WILL GIVE YOU BRAINLEST ANWSER

(use the graph)

The picture below shows the dependence of the breaking distance on its speed on a dry road (curve OA), on a wet road (curve OB), on an icy road (curve OT). Answer the following questions:

a) What is the breaking distance of the car at a speed of 50 kilometers per hour in each case?
On a dry road : m
On a wet road : m
On an icy road : m

b) What should be the car’s speed in all three cases so that the breaking distance doesn’t exceed 60 meters?

On a dry road : the highest speed should be km/h
On a wet road : the highest speed should be km/h
On an icy road : km/h

Answer 1

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
