Question

a train takes 2 hrs less for a journey of 300km if its speed is incresed by 5km/hr from its usual speed find the speed of train​

Answer 1

Answer:

let the initial speed of train=x

then final speed =x+5

and initial time be=t

then final time = t-2

hence....

xt=(x+5)(t-2)=300

=>t=100/x

(x+5)(100/x-2)=300

after solving the equation u will get ur speed of train....
