Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles.

After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.
Answer the following questions about kileys trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that kiley is at rest.
In this task you will write the ratio of miles to hours for each leg of kileys trip. You will then express the ratio as a decimal number. Next you will find the unit rate in miles per hour for each leg of the trip.
