Question

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. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. 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 Kiley’s trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that Kiley is at rest (that is, not moving).

In this task, you will write the ratio of miles to hours for each leg of Kiley’s trip. You will then, express the ratio as a decimal number. Next, you will find the unit rate in miles per hour (mph) for each leg of the trip. If your unit rate includes a repeating decimal number, you must indicate which digits repeat (for example, write 0.3 when the 3 repeats.) A description of each leg is listed below in parts A through F.


part a: the car ride from Kiley’s house to the airport

part b: at the airport, the walk from the car to the waiting area by the gate

part c: the leg from the waiting area to the airplane’s takeoff

part d: the airplane ride

part e: the walk from the airport to the cab

part f: the cab ride

Given is data about Kiley's trip to her grandmother, Answer the given question based on the data

Explanation:  

1. PART(a): the distance covered (in miles) and the time (in hours) taken to cover it in this part is  $d=24.3\ \ \ t=1$ then the ratio is ,                                   $r={243}:{10} \ \ \ \ \ \ \ r(decimal)=24.3$                                                                                   unit rate is given by,  $u=24.3 \ mph$
2. PART(b): the distance covered (in miles) and the time (in hours) taken to cover it is $d=1.2\ \ \ \ \ t=1$ then the ratio is,                                                    $r=6:5\ \ \ \ \ \ \ \ \ r(decimal)=1.2$                                                                                unit rate is given by, $u=1.2\ mph$        
3. PART(c): the distance covered (in miles) and the time (in hours) taken to cover it is $d=0.1\ \ \ \ \ t=0.25$ then the ratio is,                             $r=2:5\ \ \ \ \ \ \ r(decimal)=0.4$                                                                                          unit rate is given by, $u=0.4\ mph$
4. PART(d): the distance covered (in miles) and the time (in hours) taken to cover it is $d=346\ \ \ \ \ t=1$ then the ratio is,                                   $r=346:1\ \ \ \ \ \ \ \ r(decimal)=346.0$                                                                       unit rate is given by, $u=346\ mph$  
5. PART(e): the distance covered(in miles) and the time (in hours) taken to cover it is $d=1.1\ \ \ \ \ \ \ \ t=0.5$  then the ratio is,                                              $r=11:5\ \ \ \ \ \ \ \ \ r(decimal)= 2.2$                                                                            unit rate is given by, $u=2.2\ mph$  
6. PART(f): the distance covered (in miles) and the time taken (in hours) taken to cover it is $d=12.3\ \ \ \ \ \ \ \ t=0.25$ then ratio is,                                     $r=246:5\ \ \ \ \ \ \ \ \ r(decimal)=49.2$                                                                  unit rate is given by,        $u=49.2\ mph$
