when speed = 25m/sec, time elapsed = 25/10 = 2.5 sec
distance travelled by stone = 10*(2.5)^2 = 62.5 mts
so distance of stone above ground = 200-62.5 = 137.5 mtrs

the second. If the product of the two smaller numbers
is 85 and the product of two larger numbers is 115.
Find the middle number? | [
"11",

2y = x+z.....................1
Given that the product of two smaller numbers is 85
x y = 85................2
Given that the product of two larger numbers is 115
y z = 115...............3
Dividing 2 and 3 x y /y z = 85/115
x / z = 17 / 23
From 1
2y = x+z
2y = 85/y + 115/y
2y2 = 200
