the correct question is
Ravi is driving 440 miles to visit his grandma. if he drives at an average rate of 55 miles per hour, how many hours will it take him to get 3/4 of the way there?
we have that
3/4 of the way--------------> (3/4)*440=330 miles
I apply a rule of three
if 55 miles----------------> 1 hour
330 miles--------------> X
X=330/55=6 hour
the answer is 6 hour
