when will train b catch up with train b if train a is traveling 60 mph and passes station at 1:25pm While train b is traveling 80 mph and passes staion at 1:40pm?

Answer 1

Assume a starts, and then 15 min later, b starts.

positionA=60*t
positionB=80(t-.25) where t is in hours.

but both are at the same position...so

60t=80t-20
t=1hr

so they catch up at 2:25. Check my thinking.
