Question

I am giving 50 points for this question
please give correct answers


study the graph and answer the following

a) which of the three is the fastest
b) are all the three ever at the same point on the road
c) how far has c travelled when b passes a
d) how far has b travelled by the time it passes c

hope some1 can help me
if it's correct I will mark it as brainliest

Answer 1

Heres your Answer Mate ...

(a). 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 the 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-(0.57×3.75km) = 9.14-2.1375= 7.0025

= 7 km approx

Thus when A passes B , C travels 7km.

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

Therefore , B travelled about 5.38 km when passes C.

Hope it Helps!!

Answer 2

Hy there,
A. Fastest one can be found by calculating the speed of a, b and c.
Formula of speed is distance divided by time.
Let's see each one's speed one by one
A=6/2=3km/hr
B=12/1.4=8.57km/hr
C=10/1.8=5.5km/hr
Hence, B is the fastest

B. All of them never came at the same point.
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.

Hope it helps.
Thanks.
