Diameter of Ferris Wheel = 200 feet
a) Distance around Ferris wheel
The distance around Ferris wheel is given by the circumference of Ferris wheel.
b) Formula to calculate circumference

where d is the diameter of he wheel.
c) Distance traveled in one rotation

Answer:
The answer to the question is
1.5 hours that is;
When the distance between them is more then 135 miles is after 1.5 hours and they will lose radio contact at 3:30 p.m.
Step-by-step explanation:
We note that
The speed of the military convoy headed north =50 mph
The speed of the convoy headed south = 40 mph
Let t be the time taken for the two convoys to be 135 miles apart
The time taken for the two convoys to be 135 miles apart is given by
50×t miles+ 40×t miles= 135 miles
That is 90×t miles = 135 miles
t = 135/90 = 1.5 hrs
