Answer:
1/3 hr or 20 min.
Step-by-step explanation:
Call the trains A and B
Remember d = rt
Distance train A travels is 80t
Distance train B travels is 70t
Now, 80t + 70t = 50
150t = 50
t = 50/150 = 1/3 hr or 20 min.

the x values don't repeat
(14,7,21,28,35)
Consider that long row as 1 big rectangle with base 6+11+6+11=34 and height of 8
area=34*8=272 ft^2
the 2 rectangles on side
the sbase is 11
the height is 6 since it has to match with the other 2 side things
2*6*11=132
add to find total
132+272=404 ft^2
