We know that the total distance travelled by Vishal is 1900 km.
Therefore let us assume that the distance travelled by bus is x km.
And the distance travelled by plane is (1900-x)kms.
We also know that the total time taken to complete the journey is 5 hrs.
Therefore let us assume the time taken to complete the journey by bus is y hrs.
And the time taken to complete the journey by plane is (5-y)hrs.
It is given that,
Speed of the bus= 60km/hr
Speed of the plane= 700km/hr
As we know,
Distance=speed*time
Therefore, for bus
X=60*y---------eqn(1)
For plane,
(1900-x)=700*(5-y)-------------eqn(2)
Solving these two equations we get x=150 kms
Therefore the distance travelled by bus is 150km.
Therefore let us assume that the distance travelled by bus is x km.
And the distance travelled by plane is (1900-x)kms.
