How many miles was the trip back? ** The trip back was 30*.2=<<30*.2=6>>6 miles longer than the trip there.
How many miles was the trip back? ** So it was 30+6=<<30+6=36>>36 miles.
How many miles was the total drive? ** So the total drive was 30+36=<<30+36=66>>66 miles.
How long did she spend away from home? ** That means she drove for 66/44=<<66/44=1.5>>1.5 hours.
How long did she stay at her friend's house? ** She stayed with her friend 30/60=<<30/60=.5>>.5 hours.
How long did she spend away from home? ** So the total time was 1.5+.5=<<1.5+0.5=2>>2 hours.
