A group of friends go on a 3-hr bike ride together. They ride 15 km with the wind at their backs and then 15 km straight into the wind. The wind adds or subtracts 3 km/hr from their speed. Calculate the average speed of the group of friends with no wind.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
