Question

A photographer takes a picture of a train which is travelling at 40m/s. If the camera takes 0.01 s to take the picture, how far does the train travel in this time?

Answer 1

Answer:

Use the relation S = vt

Explanation:

S = (40) (0.01)     = 0.4 meter

hence 0.4 metre of distance will be traveled by the train in 0.01 second

Answer 2

Answer: 0.4 m = 40 cm

Explanation:

Distance travelled = Average speed x time taken

                                = 40 m/s x 0.01 s

                                = 0.4 m

                                = 40 cm
