Question

a train covered a certain distance at a uniform speed if the train would have been 10 km /h faster .it would have taken 2 hours less

Answer 1

Answer:

600kms

Step-by-step explanation:

Let distance be = X

let speed = Y

(X/Y) is the normal time taken

Now if speed is 10 km more

(X/Y+10) is the new time taken

(X/Y+10) - (X/Y) = 2

Now if speed is 10 km less

(X/Y) - (X/Y-10) = 3

Calculating we get

Y = 50 Km/Hr

Substituting for Y=50 we get

X = 600 KM

So distance is 600 Kms
