19.5+7.5= 27.0

27+ 24=51*

*I am pretty sure you are wrong.. not to be rude or anything.

I am pretty sure the answer is 51 because you have to line up the decimals when you add.

A train heads south out of Bloomington an hour after a northbound train
ahrayia [7]

9514 1404 393

Answer:

  • northbound: 2.5 hours
  • southbound: 1.5 hours

Step-by-step explanation:

When the second train leaves the station, the trains are already 63 miles apart. The rate of increase of their separation is (57 +63) = 120 miles per hour. The remaining 243-63 = 180 miles of separation will be achieved in ...

  (180 mi)/(120 mi/h) = 1.5 h

The northbound train will have traveled 2.5 hours; the southbound train will have traveled 1.5 hours when the trains are 243 miles apart.
