Answer:
t = -------------(1)
The value of t is, hour
Step-by-step explanation:
The 1st train travels at mph whereas the 2nd train travels at
mph. The trains are headed towards each other. They are s miles apart. In 1 hour their distance is reduced by
mile
So, in t hour their distance is reduced by mile.
Now if the two trains meet after t hour of starting, then,
⇒ t = -------------(1)
If s = 250 unit, = 60 unit and,
= 40 unit , then,
from (1), t = (250/(60 + 40)) hour = hour ----(2)
