The units of measure will help you understand what to do.
You want an answer in terms of time, specifically in terms of hours.
You know the vehicle is traveling at 80 km/hr.
You know the vehicle travels 210 km.
So, to end up with answer in hrs, you need to divide 210 km by 80 km/hr.
.
You also could apply the fundamental distance equation:
d = r*t
t = d/r
.
210/80 = 21/8 = 2 5/8 hr
.
5/8 hr * 60 min/hr = 300/8 min = 37.5 min
.
t = 2 hr 37.5 min
.
Done.
