A tiger is $50$ leaps of its own behind a tree. The tiger takes $5$ leaps per minute to the deer's $4.$ If the tiger and the deer cover $8$ meter and $5$ meter per leap respectively, what distance in meters will the tiger have to run before it catches the deer$?$

Best answer
Tiger covers $40$ meter/minute
Deer covers $20$ meter/minute
Relative speed of tiger is $20$ meter/minute

Deer is ahead of the tiger by $50\times 8=400$ meters
Time taken $=400/20=20$ minutes
In 20 minutes tiger covers $20\times 40=800$ meters

Correct Answer: $800$

Tiger (runs) -->                                 Deer (runs) --->

Tiger----------------------------------------Tree--------------------------Tiger catch Deer (here)

|---------------------50 Leaps --------------|-------------x m-----------|

                        50*8 = 400 m .       

|--------------------------------------------400 + x -------------------------|

 

Tiger(speed)=8*5=40m/s

Deer(speed)=5*4=20m/s

after t time tiger catch deer

t=(400+x) / 40 (tiger)

t=x / 20 (deer)

(400+x) / 40 = x/20

x=400

total time to catch deer = 400+x

 = 400 + 400

= 800
