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?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 3 minutes and 31 seconds
Relative speed of the cyclists P and Q = 12 - 8 = 4 m/s(Since they are cycling in the same direction).
Time taken to overtake= Distance/Relative Speed
⇒ Time after which they will overtake = 844/4
⇒ 211 sec
⇒ 3 min and 31 sec
