Question

On a highway, lighting poles are 50m apart. How many lighting poles will be passed by a bus that is moving at a speed of 45kmph in 4 hours?

Answer 1

Distance covered by the bus in 4 hours = 45kmph×4hrs
                                                          =180000m
Lighting poles he will cross = 180000÷50-1
                                        = 3600-1
                                        =3599
