Answer 2

Answer:

36 km/hr

Step-by-step explanation:

Given, Distance = 750 m

                 Time = 75 s

We know, Distance = Speed x Time

                    Speed = Distance / Time

                                = 750 m / 75 s

                                = 10 m/s

Now, we have to convert 10 m/s to km hr

                          10 m/s = 10 x 18/5 km/hr

                                      = 2 x 18

                                      = 36 km/hr
