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[tex]=1114[/tex] [tex]\text{miles}[/tex]
Time taken to cover the distance [tex]=4\text{hours}[/tex] and [tex]15\text{minutes}[/tex]
We know that,
[tex]\text{Average Speed}=\frac{\text{Total Distance}}{\text{Total time}}[/tex]
[tex]=\frac{1114}{\frac{17}{4}}[/tex]
[tex]=\frac{1114\times4}{17}[/tex]
[tex]=262.12[/tex] [tex]\text{mph}[/tex]
It is given that,
[tex]1\text{mile}=1.6\text{kilometer}[/tex]
therefore,
[tex]1\text{mph}=1.6\text{kph}[/tex]
Speed Of plane in Kilometers per hours [tex]=\text{speed in mph}\times1.6[/tex]
[tex]419.4\text{kph}[/tex]
Speed of in miles per hour is [tex]262.12[/tex] [tex]\text{mph}[/tex] and Speed in kilometer per hour [tex]419.4\text{kph}[/tex]
