A cheetah is running 90 feet per second and is 120 feet behind its prey which is running 60 feet per minute. How long will it take the cheetah to catch up?
Accepted Solution
A:
Answer:It will take 4 seconds for cheetah to catch up
Explanation:
Speed of cheetah= S1=90ft/s
Speed of the prey=S2=60ft/s
Distance between the cheetah and prey = d=120ft
Hence forming a linear equation,
Using the formula
Relative Speed= [tex]\frac{Distance}{time}[/tex]Relative[tex]Speed\times time[/tex]= Distance
Therefore,
Suppose t is the time [tex](S1-S2)\times t= d[/tex]Putting the values
(90-60)t=120
t=[tex]\frac{120}{30}[/tex]t=4 seconds
Hence it will take 4 seconds for cheetah to catch up
