Step-by-step explanation:
let the time be x hr
speed =distance/time
s=90/2
s=45km /hr 1.
s=540/x. 2.
by 1. and 2.
540/x=45
540=45x
x=540/45
x=108/9
x=12
time is 12 hr

Question:
a train moving at a constant speed covers a distance of 90km. in 2 hours. find the time taken by the train to cover a distance of 540km at the same speed ?
solution:
case - 1 : when distanced covered,d = 90 km
t = 2 hours
speed ,v = ?
speed = distance / time
= 90/2 = 45 km/ hr
case -2 when distanced covered,d = 540 km
speed ,v = 45 km / hr [ same as in case -1 ]
time ,t = ?
time = distance /speed
= 540/45
= 12 hour
therefore ;
the time taken by the train to cover 540 km
at same speed is 12 hours .
