150% of what length is 66 cm

svet-max [94.6K]

let's say is "x", thus "x" is the 100%.

we know that 66 is 150%, what is "x"?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 66&150\\ x&100 \end{array}\implies \cfrac{66}{x}=\cfrac{150}{100}\implies \cfrac{66}{x}=\cfrac{3}{2} \\\\\\ 132=3x\implies \cfrac{132}{3}=x\implies 44=x$

A runner runs around a circular track. He completes one lap at a time of t = 269 s at a constant speed of v = 4.6 m/s. What is t

AURORKA [14]

Answer:

$\boxed{\text{197 m}}$

Step-by-step explanation:

The formula relating distance (d), speed (s), and time (t) is

d = st

1. Calculate the distance

d = 269 s × 4.6 m·s⁻¹ = 1240 m

2.Calculate the track radius

The distance travelled is the circumference of a circle

$\begin{array}{rcl}C & = & 2 \pi r\\1240 & = & 2 \pi r\\\\r & = & \dfrac{1240}{2 \pi }\\\\& = & 197\\\end{array}\\\text{The radius of the track is }\boxed{\textbf{197 m}}$
