Aboat cruise is 30 1/3 miles long. there are 40 sight-seeing stops evenly spread throughout the distance. the boat went 2/7 of the cruise when it was forced to stop because of bad storms.

If the question is how many sight seeing stops did it make here is the -

distance between each stop = 30 1/3 / 40  =  91/120 miles

30 1/3  * 2/7 =  26/3 miles

number of stops before the storm =  26 / 3  / 91/120
                                                       = 26/3  *    120/91
                                                       = 80/7
                                                        = 11 stops
