Answer to Question #200452 in Physics for Ibrahim khan

Question

imagine that you are in the car,driving along a main road along the road,there are signs telling you how far it is to the next town at the roadside,there may be marker posts every 100 meters.Describe how you could use these roadsigns to work out the average speed of the car.

Answer 1

The average speed of the car

$$v=\frac{s}{t}\\v=\frac{100n}{t_1+t_2+⋯t_n}$$

where t₁ is time in seconds, during which the car passes the first 100 m, t₂ is time in seconds, during which the car passes the second 100 m, t_n is time in seconds, during which the car passes the latest 100 m.
