a girl wants to count the steps of a moving escalator which is going up. if she is going up on it, she counts 60 steps. if she i

Leto [7]

Let

x--------> the speed of the girl in step

y--------> the speed of the escalator in step

d------> the distance between ground and floor.

we know that

$speed=\frac{distance}{time} \\ \\ time=\frac{distance}{speed}$

when the girl is going up on escalator

$x-y=\frac{d}{60}$ ----> equation $1$

when the girl is going down on escalator

$x+y=\frac{d}{90}$ -------> equation $2$

Adds equation $1$ and equation $2$

$2x=\frac{d}{60} +\frac{d}{90} \\ \\ 2x=\frac{5}{180} d$

$x=\frac{5}{360}d$ --------> equation $3$

Time to climb (in step) with y=0 (escalator standing still)

$x*t=d\\\\ t=\frac{d}{x}$ -----> equation $4$

Substitute equation $3$ in equation $4$

$t=\frac{d}{\frac{5d}{360}} \\ \\ t=\frac{360}{5} \\ \\ t=72 steps$

therefore

the answer is

$72 steps$

48/6=192/24

all u have to do is solve the first part 48/6 which equals 8 and time that by 24. if u want to go deeper into it and show that u really understand then check ur work by dividing 192 by 24 which of course equals 8
