1 1/99 1 1/100 it takes a boat 3 hours to travel down a river from point a to point b, and 5 hours to travel up the river from b to a. How long would it take the same boat to go from a to b in still water? an airplane flies against the wind from a to b in 8 hours. The same airplane returns from b to a, in the same direction as the wind, in 7 hours. Find the ratio of the speed of the airplane in still air to the speed of the wind.

You can share whatever you create, explore what others have created and learn from each other! current sat through january 2016 download a real, full length sat practice test, watch sal work through real sat problems, and get even more practice using our interactive exercises. Six students, along with their coach, are invited to participate in a day full of mathematics and fun. Students will take part in individual and team events covering topics in geometry and algebra. As always, we will have lots of prizes to raffle off and every student and coach?? will go home with a prize! lunch and a continental breakfast will be provided the day of the competition. If you would like more information about this event, please contact dana sammons at [email protected] or 616 234 4085.
