Question

5. ssm How long does it take a plane, traveling at a constant speed of 110 m/s, to fl y once around a circle whose radius is 2850 m

Answer 1

162.71 s

Step-by-step 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
