Well, we know the eagle does 50 miles in 1hr, how long will it be for 125 miles?
well
so, the eagle for 125miles does them in 5/2 hours or 2hrs and a half
now, how far will the sterling go in 2hrs and a half?
well, we know the sterling does 75 miles in 1hr
thus
solve for "x"
Using the combination formula, it is found that if the first flag is orange then the number of different signals consisting of 4 flags is 364.
The order in which the flags are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:
In this problem, considering that the first flag is orange, 3 flags will be chosen from a set of the remaining 14, hence the number of signals is given by:
