It will take 60 seconds to move one end to the other.
The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other terms, it is a measurement of an object's motion's speed without direction Velocities are what we get when speed and direction are combined.
Given the speed of a person = 21 feet in 7 seconds
speed in per second = 21/7 = 3 feet per second
distance of sidewalk = 180 feet
speed = distance/time
time = distance/speed
time = 180/3
time = 60 seconds
Hence it will take 60 seconds to cover the distance.

Answer: 1/3 is the simplest form.
Step-by-step explanation:
All I did was see if 60 could be divided into 20, and it can.
60 divided by 20 = 3
Now I have to do the same with the 20.
20 divided by 20 = 1
Now I have 1/3.
Thats how I solved it.
Hope that helps!
