Question

if a man walks at the rate of 2 feet per second, how many minutes will it take him to walk 4320 feet?

Answer 1

Ok so if a man walks 2 ft per second you would want to find out how many seconds it takes to walk 1 foot so it takes .5 seconds to walk one foot so then you multiply 4320X.5 which then equals 2169 seconds then divide that by 60 which equals 36min. 

Answer 2

Answer: 36 minutes

Step-by-step explanation:

The formula to find the speed is given by :-

$\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}$

Given : A man walks at the rate of 2 feet per second .

Distance covered by him = 4320 feet

Let t be the time taken by him to walk 4320 feet, then we have

$2=\dfrac{4320}{t}\\\\\Rightarrow\ t=\dfrac{4320}{2}=2160\text{ seconds}$

Since 1 minute = 60 seconds

Then , $t=\dfrac{2160}{60}=36\text{ minutes}$

Hence, it will take him 36 minutes to walk 4320 feet .
