Question

ANWSER NOW A shopping mall has a moving sidewalk that takes shoppers from the shopping area to the parking garage, a distance of 220 ft. If your normal walking rate is 6 ft/s and the moving sidewalk is traveling at 4 ft/s, how many seconds would it take for you to walk from one end of the moving sidewalk to the other end?

Answer 1

Answer:

It would take 22 seconds to walk from one end of sidewalk to the other.

Step-by-step explanation:

i) distance from the shopping area to the parking garage = 220 feet

ii) normal walking rate = 6 ft / second

iii) moving sidewalk = 4 ft/second

iv) total speed therefore  = 6 + 4 = 10 ft/second

v) number of seconds to walk from one end of sidewalk to the other

 = 220 ft / (10 ft/second) = 22 seconds.
