ANSWER
(a) Since the slope of line B is the greatest, B is travelling at the fastest speed.
(b) Since the three lines do not intersect at a single point, the three objects never meet at the same point on the road.
(c) Since there are 7 unit areas of the graph between 0 and 4 on the Y axis, 1 graph unit equals 4/7 km.
Since the initial point of an object C is 4 graph units away from the origin, Its initial distance from the origin is 4*(4/7)km = 16/7 km
When B passes A, the distance between the origin and C is 8km
Therefore, total distance travelled by C in this time = 8 – (16/7) km = 5.71 km
(d) The distance that object B has covered at the point where it passes C is equal to 9 graph units.
Therefore, total distance travelled by B when it crosses C = 9*(4/7) = 5.14 km
Answer:
(a) B will be travelling farthest
(b) No
