Solving for the elapsed time
distance traveled = (speed of first train + speed of second train) * elapsed time
280 miles = (95 mph + 105 mph) * elapsed time
280 miles = 200 mph * elapsed time
elapsed time = 280 miles / 200 mph
elapsed time = 1.4 hours
elapsed time = 1 hour and 24 minutes
It will take 1 hour and 24 minutes for the two trains to be 280 miles apart.

Answer:
Area of Poster = 23 sq inches
Step-by-step explanation:
Let say Width of Rectangular Poster = W inches
then Length of Rectangular Post = 2W inches
Perimeter = 2 ( W + 2W) = 6W inches
Perimeter given = 12 inches
Equating both
6W = 24
=> W = 4
Width of Poster = W = 4 Inches
Length of Poster = 2W = 2 * 4 = 8 inches
Area of Poster = 4 * 8 = 32 sq inches
