An express train takes 1 hr less than a passenger train to travel 132

1.	An express train takes 1 hr less than a passenger train to travel 132 km between Mysore and Bangaluru. If the average speed of the express train is 11 km / hr more than that of a passenger train. Then find the ratio of the speed of the two trains.
Answer» ANSWER: SPEED of passenger train = 33 km/hr, speed of EXPRESS train = 44 km/hr Let the AVERAGE speed of the passenger train be x km/hr. Then the average speed of express train = (x+11) Time taken by passenger train = x 132 hr Time taken by express train = x+11 132 hr = ( x 132 −1)hr ⇒x 2 +11x−1452=0 ⇒(x−33)(x+44)=0 ⇒(x−33)=0 or (x+44)=0 ⇒x=33 or x=−44 Speed can not be NEGATIVE, ⇒x=33, x+11=44 Hence, the speed of passenger train =33 km/hr and the speed of express train =44 km/hr please mark me as brain list

Answer»

ANSWER:

SPEED of passenger train = 33 km/hr, speed of EXPRESS train = 44 km/hr

Let the AVERAGE speed of the passenger train be x km/hr.

Then the average speed of express train = (x+11)

Time taken by passenger train =

132

Time taken by express train =

x+11

132

hr = (

132

−1)hr

⇒x

+11x−1452=0

⇒(x−33)(x+44)=0

⇒(x−33)=0 or (x+44)=0

⇒x=33 or x=−44

Speed can not be NEGATIVE,

⇒x=33, x+11=44

Hence, the speed of passenger train =33 km/hr and the speed of express train =44 km/hr
