Using proportions, it is found that the speed of the runners are of 16 mph and of 20 mph.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
After 30 minutes, the runners are 2 miles apart, hence the second runner is 4 miles per hour faster than the second, that is:
.
The first runner's speed is 4/5 of the speed of the second runner, hence:
Hence, the speed of the runners are of 16 mph and of 20 mph.

the correct question is<span>
The product of two consecutive even integers is 120. Find the integerslet
x-----------> first even integer
x+2-------> second consecutive even integer
we know that
x*(x+2)=120-------> x</span>²+2x-120=0
<span>
using a graph tool----> to resolve the second order equation
see the attached figure
the solution is
x=10
therefore
</span>first even integer is 10
second consecutive even integer is (10+2)----> 12
<span>
the answer is10 and 12</span>
