"Let x represent the distance Emilio drives at 60km/h and y represent the distance he drives awn 90km/h"

                SPEED        TIME           DISTANCE

Part1           60                          x

Part2           90                          y

Total                                 350

Fill in the missing time information.

                SPEED        TIME           DISTANCE

Part1           60                          x

Part2           90                          y
