On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?
Answer:
The Flight took 1.6 hrs or 1 hour and 36 minutes to travel 800 miles.
Step-by-step explanation:
Given:
An equation relating the distance traveled in miles [tex]d[/tex] to the number of hours flying [tex]t[/tex] is:
[tex]t=\frac{1}{500}d[/tex]
We need to find the time required to travel distance of 800 miles.
Solution:
So we can say that;
[tex]d=800\ miles[/tex]
Now Substituting the value of 'd' in given equation we get;
[tex]t= \frac{1}{500}\times800\\\\t=\frac{8}{5}\\\\t=1.6\ hrs[/tex]
Now we know that;
1 hour = 60 minutes.
1.6 hours = Number of minutes in 1.6 hrs.
Using Unitary method we get;
Number of minutes in 1.6 hrs = [tex]1.6\times60 =96\ mins[/tex]
96 mins can be written as = 60 mins + 36 mins = 1 hours and 36 mins.
So we can say that;
The Flight took 1.6 hrs or 1 hour and 36 minutes to travel 800 miles.
