Gabriella drives her car 360 miles and averages a certain speed, If the average speed had been 6 mph less, she could have traveled only 330 miles in the same length of time. What is her average speed?

distance/ rate = time

360 / r = time

330/ (r-6) = the same time

360/r = 330(r-6)

360(r-6) = 330 r

30r = 2160

r=72 m/hr
