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.

I tried 1.6 but it does not work

It's 7.2 m/s buh gives 2 marks

I apologise sincerley

To calculate the average speed of the car, we need to use the formula:

Average Speed = Distance / Time

First, let's determine the distance traveled by the car. Since the marks on the road are 0.8 meters apart, the distance between Photo 1 and Photo 2 is 0.8 meters.

Next, we need to find the time it took for the car to travel this distance. Given that Photo 2 was taken 0.5 seconds after Photo 1, we know that the time elapsed is 0.5 seconds.

Using these values, we can now calculate the average speed:

Average Speed = Distance / Time
Average Speed = 0.8 meters / 0.5 seconds

Dividing 0.8 meters by 0.5 seconds gives us an average speed of 1.6 meters per second (m/s).

Therefore, the average speed of the car is 1.6 m/s.

have you found the answer

0.8m/0.5s = 1.6 m/s
