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.

Answer:

here ....x = 2 and y = 3

$= xy - y + x \times x$

$= 2 \times 3 - 3 + 2 + 2 \times 2$

$= 6 - 3 + 2 + 4$

$= 12 - 3$

$= 9$
