Answer:
8 hours
Step-by-step explanation:
there are 360 miles total because it already covered 160 and there are 200 left. 160 / 4 = 4 hours per 40 miles. 200 is 40 more miles than 160. This means that it is the 4 hours of 160 miles in that 200 + 4 more hours for 40 miles. Add them together and you get 8 hours.
