Two persons P and Q are 844 m apart. They both start cycling simultaneously in the same direction with speeds of 12 m/s and 8 m/s, respectively. In how much time will P overtake Q?
Answer & explanation
Correct answer: option 2
Distance b/w P & Q = 844 m
Relative Speed = ( 12 - 8 ) = 4 m/sec
( when they moves in same direction)
Time taken by P to overtake Q = \(\frac{844}{4}\) = 211 sec
SO , Time taken by P to overtake Q is 3 minutes 31 seconds .
