Answer 1

Hope you get the answer

Sorry for answering late.

Answer 2

mark me as brainliest answer

Solution:

Let the speed of passenger train is x kmph

and that of express train is y kmph

Distance = 168 km

Time taken by Express train to travel between akola to bhusawal = 168/y hour

Time taken by passenger train to travel between akola to bhusawal = 168/x hour

According to the question Express train taking 1 hour less

168/y+1 =168/x

168+xy=168y

168x-168y+xy=0 equation........ (1)

according to question

y = x + 14 equation............. (2)

Substitute from eq 2

168x-168y+xy=0

168x-168(x+14) +x(x+14) =0

168x-168x+2352+x^2+14x=0

x^2+14x-2352=0

x2+56x+42x-2352=0

x(x+56)42(x-56) =0

(x+56) (x-42)

negative value can be discarded.

Thus Speed of passenger train 42 kmph

Speed of express train = 42+14= 56 kmph

Hope it helps you.
