Two leaves chicago at same times different directions one going 60 other going 65 how long before they reach 375 apart

ANSWER:  

Both the trains are 375 miles apart after 3 hours of journey.

SOLUTION:

Given, two trains leave Chicago at the same time in different directions,

Let the two trains be train A, train B.

And speed of train A is 60 miles per hour  

Speed of train B is 65 miles per hour

We need to find time after which distance between two trains becomes 375 miles.

Let the time at which they are 375 miles apart be "t",

And distance traveled by A be "x", then distance traveled becomes 375 – x.

We know that, distance traveled = speed time

For train A:

x = 60t --- eqn (1)

For train B :

375 – x = 65t  -- eqn 2

Substitute (1) in (2)

375 – 60t = 65t

375 = 65t + 60t

125t = 375

t = 3

hence, both the trains are 375 miles apart after 3 hours of journey.
