Find the Displacement

A block slides 30 m at a constant velocity of 20 m/s.
How much time did the trip take?

The trip time taken by the box is 1.5 sec.

Explanation:

Given:

                                       distance(d) = 30 m

                                        Velocity(v) = 20 m/s

By using formula:

                                    Velocity =

                                        or, 20 =

                                       or, time(t) =

                                     ∴ time (t) = 1.5 sec

Hence the the block took 1.5 sec to slide 30 m.
