(1)  To find the time (to find "how many seconds will it take"),


     divide the distance by the speed; in other words, divide 4500 meters by 2.5 meters per second.



(2)  2.5 m/s = %282.5%2A3600%29%2F1000 kilometers per hour.


      Remember (!) :   1 hour = 3600 seconds.

                       1 kilometer = 1000 meters.
