Each week, Rosario drives to an ice skating rink that is 60 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?

Answer:

60 miles/55 mph = 1 1/11 hours (about 1.09 hours) from home to rink

2 3/4 - 1 1/11 = 2 33/34 - 1 4/44

= 1 29/44 hours (about 1.66 hours) from rink to home

60 miles / (73/44) hours = about 36.14 mph from rink to home
