The distance between the two cities is 1114 miles. a.What is the average speend of the plane in miles per hour? b.If every mile is approximately 1.6 kilometers, what is the speed of the airplane in kilometers per hour?

Answer 1

Answer:

262.12mph and 419kph

Step-by-step explanation:

Given: It takes 4 hours and 15 minutes to fly from Orlando, Florida, to Boston, Massachusetts. The distance between the two cities is 1114 miles

To Find: the average speend of the plane in miles per hour, If every mile is approximately 1.6 kilometers, the speed of the airplane in kilometers per hour

Solution:

Distance between Orlando,Florida and Boston, Massachusetts$=1114$ $\text{miles}$

Time taken to cover the distance $=4\text{hours}$ and $15\text{minutes}$

We know that,

$\text{Average Speed}=\frac{\text{Total Distance}}{\text{Total time}}$

                                          $=\frac{1114}{\frac{17}{4}}$

                                          $=\frac{1114\times4}{17}$

                                          $=262.12$ $\text{mph}$

It is given that,

$1\text{mile}=1.6\text{kilometer}$

therefore,

$1\text{mph}=1.6\text{kph}$

Speed Of plane in Kilometers per hours $=\text{speed in mph}\times1.6$

                                                                   $419.4\text{kph}$

Speed of in miles per hour  is $262.12$ $\text{mph}$ and Speed in kilometer per hour  $419.4\text{kph}$
