Each week, Rosario drives to an ice skating rink that is 120 miles away. The round-trip takes 2.75 hours. If he averages 55 miles per hour on his way to the rink, which equation can be used to find \( x \), the number of miles per hour he averages on his way home?

120/(2.75-(120/55))= x the mph on the way home

The required equation is 2.75 = 55 120 ​ + x 120 ​
The value of x is 211.2 miles per hour. ;
