MULTIPLE CHOICE QUESTION
Which distance-time graph most
accurately represents the data in the
data table?

Sagot :

Answer:

(a) The slope of distance-time graph gives the speed of the objects.

           As the slope of object  (B) is the greatest among all, thus  B has the largest speed and hence it is the fastest among all the objects.

(b)  :      As the curve of the objects do not intersect with each other even once, hence they cannot be at the same point on the road at the same time.

(c)   :      On the y axis  (i.e.  distance line), 7 small represents 4 km

      ∴  1 small line  =  

7

4

​  

=0.57 km

           Position of C at the instant B passes A is  8 km

       

(d)   ;     Position of B at the instant it passes C is 2nd small line above 4 km i.e. 4+2×0.57=5.14 km  

       ∴ Distance traveled by B   =5.14−0=5.14 kmV
