Answer in km/h·s

(120 km/h)divided by 7s will give you the answer in units of km/(h.s)

I think it's the wrong answer because I plugged it in and it was still marked wrong.

I would use two significant figures and choose 17 km/h.s for the answer. If it isn't accepted, there is something wrong with test grading system

you must convert it to m/s
