During a training exercise, a submarine travels 16 km/h on the surface of the water and 10 km/h underwater. If the submarine travelled a distance of 160 km in 12.5 hours, how
long was it underwater?

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′.
