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