On a vacation, DeVante and his family traveled 382 miles at 64 mph. How long did the trip take? (Round to the nearest hundredth)

Ilya [14]

Okay. I'm sure you are familiar with the DST triangle, yes? It will help you solve this problem. Distance/speed = time. 382/64 = 5.96875. Round to the nearest hundredth to get 5.97 hours.
