Question

Two trains leave stations 180 miles apart at the same time and travel toward each other. One train travels at 85 miles per hour while the other travels at 65 miles per hour. How long will it take for the two trains to meet?Hours=

Answer 1

Let t be the time in hours for which the two trains meet, then we can set the following equation:

$85t+65t=180.$

Solving for t we get:

$\begin{gathered} 150t=180, \\ t=\frac{18}{15}=\frac{6}{5}\text{.} \\ t=1.2. \end{gathered}$

Answer: 1.2 hours.
