On a bike trip across the united states rodney notes that he covers about 190 miles every 4 days if he continues this rate use a ratio table to determine about how many miles he could bike in 6 days

Rodney travels a distance of 190 miles in 4 days.
The question wants to find the distance Rodney can travel in 6 days.
Distance travelled by Rodney in 1 day = (190/4) miles
                                                             = 47.5 miles
Distance travelled by Rodney in the 2nd day = (47.5 * 2) miles
                                                                       = 95 miles
Distance travelled by Rodney on the 3rd day = ( 47.5 * 3) mi;es
                                                                     = 142.5 miles
Distance travelled by Rodney on the 4th day is given and it is 190 miles.
Distance travelled by Rodney on the 5th day = ( 47.5 * 5) miles
                                                                        = 237.5 miles
Distance travelled by Rodney on the 6th day = (47.5 * 6) miles
                                                                       = 285 miles
So this can be put as a ratio table and the distance travelled by Rodney on the 6th day is 285 miles.

Ithink it is b and d
