Question

6. Fig 8.11 shows the distance-time graph of three objects A.13
and C. Study the graph and answer the following questions:
(a) which of the three is travelling the fastest ?
(b) are all three ever at the same point of the road ?
(c) how far has C travelled when B passes A ?
(d) how far has B travelled by the time it passes C ?​

Answer 1

Answer:

(a) It is clear from graph that B covers more distance in less time. Therefore, B is the fastest.

(b) All of them never come at the same point at the same time.

(c) According to graph; each small division shows about 0.57 km.

A is passing B at point S which is in line with point P (on the distance axis) and shows about 9.14 km

Thus, at this point C travels about

9.14 – (0.57 x 3.75) km = 9.14 km – 2.1375 km = 7.0025 km ≈ 7 km

Thus, when A passes B, C travels about 7 km.

(d) B passes C at point Q at the distance axis which is ≈ 4km + 0.57km x 2.25 = 5.28 km

Therefore, B travelled about 5.28 km when passes to C.
