Chapter 5, Problem 14TP
Solution

To calculate: The speed of the escalator if L walks at a speed of 6 feet per second and the trip took 9 seconds.

The speed of the escalator is 2 feet per second or 4 feet per second.

Given information:

L steps onto an escalator and begins descending. After riding for 12 feet, she realized that she dropped her keys on the upper floor and walks back up the escalator to retrieve them. The total time T for her trip down and up the escalator is given by the equation:

  T=12s+12ws , where s is the speed of the escalator and w is L's walking speed.

Calculation:

Consider the equation T=12s+12ws.

Substitute T=9 and w=6 and solve for s.

  9=12s+126s

Take LCD and multiply both sides by LCD.

  9s6s=12ss6s+126ss6s9s6s=126s+12s54s9s2=7212s+12s9s254s+72=0s26s+8=0            Take 9 as common

Factorize.

  s22s4s+8=0ss24s2=0s4s2=0

So, s=4 or 2

Therefore, the speed of the escalator is 2 feet per second or 4 feet per second.
