Question

a bus go with a certain distance with uniform speed if the speed of the bus would have been increased by 50 km per hour.If would have 2 hours less to cover same distance if the speed of bus would have been decreased by 5 km per hour it would have been one hour more to cover some distance .find distance covered by bus?​

Answer 1

Answer:

Let speed and distance traveled by bus be x and y respectively

Now from question we get,

x+15

y

=

x

y

−2 and

x−5

y

=

x

y

+1 using [Speed=

time

distance

]

From the second equation, we get,

5y=x(x−5) ....(i)

From above first equation we get y=

15

2x(x+15)

,

by putting this in equation (i) we get x=45

which gives distance y as 360km
