It takes Lois 1.5 h longer to go to her friend's house than it does to return home. How many hours did it take Lois to ride to her friend's house?

Let the number of hours be x

She goes at 10mi/h
Gets a ride at 25mi/h

1.5 hour longer =1.5+x

Expression:
10(x+1.5)=25x
10x+15=25x
15x=15
x=1

1+1.5 = 2.5

Hence, it took her 2.5h to travel to her firends house and 1h to return.
