Answer:
10 hours
Step-by-step explanation:
The rate x time of the first day + the rate x time of the second day equal the distance of 180 miles.
Let t = time
10t + 8t = 180
18t = 180
t = 10
45 minutes.(1 hour / 60 minutes)=45/60 hours=3/4 hours.
rate=paints boats/ time (hour)=340 boats / (3/4) hour=
=(340 boasts*4)/3 hour=453.333... boats/hour≈453.33 boat/hour.
