in 28 seconds. If the radius
Carolar path 15 14m calculate the average
Speed​

Answer 1

Explanation:

r=1514m

$r = 1514 \\ t = 28s \\ half \: revolution \ = 2\pi r \div 2 = \pi \: r \: \\ = (22 \times 1514 ) \div 7 \\d =33308 \div 7 = 4,758.2857m \\ \\ s = d \div t \\s = 4,758.2857 \div 28 \\s = 169.938metrepersecond$
