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.

Which is the solution to the inequality? 2 3/52 1/15 b< 3 2/15 b> 3 2/15

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
