a. Distance Avril rode her bike a total of 18 miles, from home to the library and then to the beach. The distance from Avril’s house to the library is 7 miles. What is the distance from the library to the beach?

Explanation:

The length of the route is the sum of the lengths of the parts of the route.

Let b represent the distance to the beach from the library.

total distance = (home to library) +(library to beach)

18 miles = 7 miles + b

11 miles = b . . . . . . . . . . subtract 7 miles from both sides of the equation

The distance from the library to the beach is 11 miles.
