Try 9:2 and 3:1 but I'm not sure if that's right or not
For a:
(2400*2*PI)/60(seconds) = 80 PI RAD/Sec
For b:
arc length s= radius r * central angle(in radians)
= ((80*pi*7.5)/(2*pi)
=25
so john is x and if Maya has the same as john but -3 then
x+x-3
but sam is still missing and she has half of Maya which is 0.5x - 1.5
so the equation is
x+x-3+0.5x-1.5=68
and then you add 3 and 1.5 to 68 which is
2.5x=72.5
and you divide by 2.5 which is 29
John has 29 points
Shadow length is proportional to object height.
(tower height)/(tower shadow length) = (tree height)/(tree shadow length)
(tower height)/(72 ft) = (27 ft)/(6 ft)
(tower height) = (72 ft)*(27/6)
(tower height) = 324 ft
The cellular telephone tower is 324 ft tall.
