Hi Stephanie,

The units are the key here. The problem has the distance in kilometres and the speed in metres per second. 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.
