About to leave for home from his office, a person notices a problem with his car and travels home at a speed which is less than his usual speed and takes 20% more of usual time. What is the average sp

Answer»

(5/6)th of the ORIGINAL SPEED



Time taken is 20% more than the usual time.
i.e. If t is the time, then (6/5)t is the ACTUAL time taken.
i. e. t has become (6/5)t
Hence, speed will become (5/6)s, where s is actual speed.
