The answer is 8 because in a minute there is 60 seconds so you divide 48 by 60 and it gives you 8
If the sides are in the ratio of 11:16:24, it means that they are all multiples of a same number x, according to these factors.
So, the shorter side is 11x feet long, the middle one is 16x feet long, and the longest side is 24x feet long.
This means that the perimeter is
feet long. But we know that this is 510 feet, so we have
.
So, the three sides are 110, 160 and 240 feet long.
To find the area of a triangle knowing its three sides, you can use Heron's formula, which states that, if
is half the perimeter of the triangle whose sides are
, the area
is given by

In our case,
so the formula becomes

Ok so x+4-1 makes x-1 so i belive the answer could be 1/5
You can calculate the difference/vector of both points:

then calculate the magnitude/length like pythagoras
The correct numbers are 55 and 47, because they have a difference of 8 and a sum of 102.
