Answer:
162.71 s
Explanation:
Applying,
v = 2πr/t................... Equation 1
Where v = Velocity of the plane, r = radius of the plane, t = time, π = pie.
make t the subject of the equation
t = 2πr/v................ Equation 2
From the question,
Given: r = 2850 m, v = 110 m/s
Constant: π = 3.14
Substitute these values into equation 2
t = (2×3.14×2850)/(110)
t = 17898/110
t = 162.71 s
