40% of the beads were blue which means 60% of the beads were red. If all the blue beads were used that means 40% was used so you add the 25% of the red beads that were used which is why the answer is 65%.
Wind speed: 100 miles per hour 300 times 6 = 1800 miles so it took 6 hours to travel 1800 miles. 1800 minus 1200 miles = 600 miles. you lost 600 miles over 6 hours or 100 miles per hour
