I want both length units so I am going to convert the distance of 2 kilometres to 2000 metres since there are 1000 meters in a kilometre. Now I have a distance in metres, a rate an metres/second and I want the time in seconds. Thus what I want is This is a lot of seconds so you probably should convert it to minutes and seconds.
