A speed camera takes two photographs of a car.Photo 2 was taken 0.5 seconds after Photo 1.Marks on the road are 0.8 meters apart.Calculate the average speed of the car in m/s?
7.2 m/s but when i submit answer i get 2 marks only not full 3 marks what am I doing wrong and what is the full answer?
yeah , how did u get 14.4 , and ye got this question on maths watch
It does not work
r= 0.8m/0.5s = 1.6 m/s
7.2 m/s
14.4
In every problem solving, equations, algebra, ratio; you should think mathematically. first what you would do for this question is.
0.8/0.5 = 1.6m/s
Im not going to give the answers because there are many students who doesn't care in what method there doing therefore all you people reading my comment think carefully and reply when you really don't understand. THX
