Ques:- A train 240 m long passed a pole in 24 sec. How long will it take to pass a platform 650 m long?
Recent Answer : Added by dumeel kuppam vavvaalu On 2021-08-25 14:15:33:

From the first statement
Speed=distance/time
=>240/24=10m/s
so speed=10m/s
From the second statement
distance=length of the platform+length of the train=650+240=890m
Time=distance/speed
here, the speed of the train is already calculated
=>890/10=89s
So the time taken by the train to cross the platform is 89 seconds

Recent Answer : Added by Admin On 2022-09-29 16:36:42:

answer :
Let the distance which I walk to the station be x km Then Time needed to reach the station at 3 km/hr = (3x​+602​) hrs and
Time needed to reach the station at 4 km/hr = (4x​+602​) hrs But 3x​+301​=4x​−301​⇒3x​−4x​=−302​=151​
⇒124x−3x​=151​⇒12x​=151​⇒x=1512​=54​ km
