Answer 2

They will never meet. The second train will get red signals to keep it at least one section behind. (If your teacher doesn't give you top marks for that they are a bum!)

Answer 3

a. 3.5 hours

b. 280 miles

c. 2 pm

The first train is 35 miles ahead of the second train when it leaves. The second train is 10 mph faster than the first, so it needs 3.5 hours to make up that 35 miles(70*.5=35), (80-70=10), (35/10=3.5), (3.5*80=4*70=280), The train first train left half an hour before the second, so 10 am plus 4 hours total equals 2 pm.

Answer 4

They are going the same direction, they will never meet.

The second train catches up to the first train at the first place there is track and time, dispatchers always give section men 20 minutes too long and they are always late turning them in.
