Balloon velocity is 14 ft/s upwards
Distance between balloon and cyclist is 140 ft
Velocity of motor cycle is 88 ft/s
After 10 sec
motorcyclist traveled a distance of 
Distance traveled by balloon in 10 s

net height of balloon from ground =140+140=280 ft[/tex]
at 
distance between cyclist and balloon is 

now suppose at any time t motorcyclist cover a distance of x m and balloon is at a height of h m
thus 
differentiating w.r.t time
