10-18.

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.

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.

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

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