A car travelled at a constant speed over some equally spaced lines on the road

A speed camera took two photos of the car, as shown below

The second photograph was taken 0.5 seconds after the first

Calculate the speed of the car in m/s
If your answer is a decimal, give it to 1 d.p.

Please give workings out, thank you

The speed of the car is 13.6 m/s, and the distance traveled in 5 seconds is 68 m.

To calculate the speed of the car and the distance traveled, we'll use the information provided. Let's denote the distance between lines as "d" (1.7 m) and the time between the two photographs as "t" (0.5 s).

Calculate the Speed (Velocity):

The speed of the car can be calculated using the formula:

Speed = (Total Distance) / (Total Time)

The total distance covered between the two photographs is the difference in the number of lines, which is 4 lines:

Total Distance = 4 * d

Now, we can use the formula for speed:

Speed = (4 * d) / t

Substituting the given values:

Speed = (4 * 1.7 m) / 0.5 s

Speed = 13.6 m/s

Calculate the Distance Traveled in 5 Seconds:

The distance traveled in 5 seconds can be calculated using the formula:

Distance = Speed * Time

Substituting the values:

Distance = 13.6 m/s * 5 s

Distance = 68 m

The question probable may be:

A car travelled at a constant speed over some equally spaced lines on the road The distance between equally spaced lines is 1.7m

A speed camera took two photos of the car, as shown below

The second photograph was taken 0.5 seconds after the first

Calculate the speed of the car in m/s and also the distance travelled in 5sec.
