Ravi started from town A towards town B. He travelled at a certain speed until his vehicle developed an engine problem and he had to reduce his speed by one fourth for the remaining distance. This happened when he had covered a distance of 8x km. He reached B, 1 hour later than expected. Had the problem occurred after he had covered 3x km more, he would have reached B 45 minutes late. Find the time for which he had travelled, until the problem occurred. .....
I did it like this but answer is coming wrong ... speed is u after accident =3u/4 .... now it will be 15 min late due to travelling 3x km with reduced speed 3u/4 hence 3x=(3u/4) * 15/60 ,hence x=u/16. Now
time for which he had travelled, until the problem occurred. = 8x/u =1/2 hrs ..but answer is 2 ... please explain
