Answer 1

ANSWER

= 8/75

Step-by-step explanation:

A's rate is (1/3)/5

                 = 1/15

and B's rate is (2/5)/10

                        = 2/50  

                          = 1/25.

Their combined rate is 1/15 + 1/25

                                    = 5/75 + 3/75

                                            = 8/75
