Question

A train takes 5 hours to travel a distance of 325 kilometre and other train travels at a speed which is 60 kilometre per hour more than that of the first train. How long will it take to travel the same distance?​

Answer 1

Answer:

2 hours 36 minutes is needed to travel the same distance

Step-by-step explanation:

Distance covered by train A is x = 325 km

Time taken to cover that distance  is t =5 hours

Speed of train A

$v = \frac{Distance}{ time} \\v=\frac{325}{5} \\v=65km/hr$

other train B 60 km /hr faster than train A

Speed of train B is 60+65 = km/hr

Time taken to cover the same distance 325 km is

= 325/ 125=2.6 hours = 2 hours 36 minutes

2 hours 36 minutes is needed to travel the same distance

Answer 2

solution :

=let the speed of train first=x = ,325km/hr

=we know that formula of speed : S =$\frac{distance}{time}$

=so ; $\frac{325}{5}=65$

=now speed of another train is mentioned that is 60km/hr more than the given  speed so 65km+60km=125km/hr.

=again put the same forula so we will get :  S = $\frac{325}{125}=2.6$

=hence the train will take 2 hour 36 min for cover the same distance.
