Final answer:
The food delivery driver will drive 3.25 miles east to reach the restaurant from his current location 4.75 miles west of the city's library.
Step-by-step explanation:
The student asked how a food delivery driver will drive to the restaurant given that the driver is 4.75 miles west of the city's library and the restaurant is 1.5 miles east of the library. First, we need to find out the total distance the driver will have to travel to reach the restaurant. To do this, we need to add the distance the driver is from the library to the distance of the restaurant from the library, considering their directions.
Since the driver is west of the library and the restaurant is east of the library, these distances will be in opposite directions on the same line, so we subtract:
4.75 miles (driver to library) - 1.5 miles (library to restaurant) = 3.25 miles
Thus, the driver will drive 3.25 miles east to reach the restaurant from his current location.
