Mr. Toshio had 32 rulers.
32-11 = 21 rulers.
21+4 = 25 rulers.
and
25-7 = 18 rulers
The other endpoint (x,y)
(X+18)/2 = 16 then x=14
(Y-18)/2 = -16 then y=-14
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.
