Answer 2

Distance travelled by car = 400m

Time is taken by car to cover the distance = 20sec

We know that,      

                          Speed = Distance

                                             Time

                                         =   400

                                                20

                       

                                          = 20km/sec

Hence, the speed of the car is 20km/sec
