B to A = 200 miles .........50 mph...........(200/50=4hrs)
———————————————————————-
Total =. 400 miles ........ S .....................9 hrs
S=400/9=44.444 hrs
...... ........Distance ........Speed.......Time
A to B = 200 miles .........40 mph...........(200/40=5hrs)
B to A = 200 miles .........50 mph...........(200/50=4hrs)
