### Example Question #1 : Word Problems

The first 60 miles of a 100-mile trip took one hour; the whole trip took two hours and fifteen minutes. To the nearest whole, what was the average speed during the remaining 40 miles of the trip?

**Possible Answers:**

32 miles per hour

36 miles per hour

50 miles per hour

40 miles per hour

**Correct answer:**

32 miles per hour

The average speed during a trip of miles over a period of hours is miles per hour. Here, the distance driven is 40 miles; the time it took was two hours and fifteen minutes total minus the hour for the first 40 miles, which is one hour and fifteen minutes. Since fifteen minutes is equal to

hours, we get

and

Therefore, the average speed traveled during the second part of the trip is

miles per hour.
