Answer:
The man covers 200 ft in 40 seconds.
Step-by-step explanation:
A person is moving on the sidewalk from one end to the other end.
He walks 40 feet in 8 seconds.
Therefore his speed = [tex]\frac{distance covered}{time}[/tex]
= [tex]\frac{40}{8}[/tex]
= 5 ft/[tex]s^{2}[/tex]
He covers the sidewalk distance at a rate of 5 feet every second.
To calculate the time taken to cover 200 ft,
time = [tex]\frac{distance to be covered}{speed}[/tex]
time =[tex]\frac{200}{5}[/tex]
time = 40 seconds
Hence the man covers 200 ft in 40 seconds.
