A train travels at an average rate of $40$ miles per hour and travels for $110$ miles.

1. Using what you know about distance, rate, and time, write an equation for this situation. Be sure to define your variable.

   Help (a):

   If a train traveled at $30$ miles per hour for $60$ miles, it would take $2$ hours based on the equation below.

   $t= \frac{60}{30}$

2. Use your equation to determine how long will it take the train to travel this far. Be sure to show all of your work.

   Help (b):

   Based on the expression above, how long would it take to travel $110$ miles at a rate of $40$ miles per hour?

   Answer (b):

   $2.75$ hours or about $2$ hours, $45$ minutes
