Lilly takes a train each day to work that averages 35 miles per hour. On her way home, her train ride follows the same path and averages 45 miles per hour. If the total trip takes 2.5 hours, which equation can be used to find n, the number of miles Lilly’s home is from her work?

Trip to Work
n

Trip Home
n
45 mph

StartFraction n Over 35 EndFraction times StartFraction n Over 45 EndFraction = 2.5
StartFraction n Over 35 EndFraction + StartFraction n Over 45 EndFraction = 2.5
35 n + 45 n = 2.5
35 n times 45 n = 2.5
