Question

Which car traveled at the greatest average speed ?
(image below)

Answer 1

I think it's car C can someone tell me if I'm accurate or not ?

Answer 2

Which car went the most distance in the shortest time? You would have to measure the slope to be accurate, but it's between A & C. My guess is C.

Answer 3

Car A

Answer 4

since the gradient of its line is the most steepest (i.e. most distance covered in less time)

Answer 5

Speed is the SLOPE of the line in a time/distance graph

all lines are straight so the line with the steepest slope is the highest speed

Answer 6

@FaiqRaees That's correct, but C went twice as far in a little more time. He would would have to measure the slope correct?

Answer 7

yeah but they are asking greatest average speed. It sure has taken greater distance but also spent more time.

Answer 8

BUT

The question is a little ambiguous -
Not all the cars started moving at t=0

so if you take the average from t=0 the answer may be different
