Question

Train A and B are traveling in the same direction on parallel tracks.Train A traveling at 60 miles per hour and train B is traveling 80 per hour train A passes a station at 8:15 pm if train B passes the same station at 830 pm at what time will train B catch up to train A

Answer 1

so true

Answer 2

in 15 minutes train A has gone 15 miles, and so its distance from that point is
\[15+60t\] where is time after 8:30
train B will go a distance of
\[80t\] and they will meet at the same distance so put
\[15+60t=80t\] and solve for t

Answer 3

\[15=20t\]
\[t=\frac{15}{20}=\frac{3}{4}\] so three fourths of an hour later, aka 45 minutes

Answer 4

1130

Answer 5

9:45
