A jeep finishes a journey in 9 hours at a speed of 60 km her hour. by how much speed should its speed be increased do that it may only take 6 hours to finish the journey??

90 km / hour.

Step-by-step explanation:

Speed = distance / time

So Distance = speed * time.

The distance is the same  in both scenarios so

60 * 9 = s * 6   where s is the required speed.

540 = 6s

s = 540 / 6

s = 90 km / hour.

90 km/h

Step-by-step explanation:

If the jeep finished the journey in 9 hours and 60 km/h, then we know that the journey is 9 * 60 kilometers long, or 540 kilometers.

540 kilometers / 6 hours = 90 km/h

3y = 6 - 2 ( 0 ) take

x zero and find value of y

3y = 6 - 2 ( 0 )

3y = 6 - 0

3y = 6

both sides divide by 3

ans : y = 2

now we can find so the value of x

3y = 6 - 2x

3( 0 ) = 6 - 2x

when we find the value x we take y ( 0 ) zero

3 ( 0 ) = 6 - 2x

0 = 6 - 2x

0 + 6 = - 2x

6 = -2x

both sides divide by -2

ans or value of x is 3

Step-by-step explanation:

first

- find one of the values of x and y

two :

- when you solving this

take y ( 0 ) if you search / find the value of X
