Question

Out of 1900 km , Vishal travelled some distance by bus and some by aeroplane. Bus travels with average speed 60 km/he and the average speed of aeroplane is 700 per hr . It takes 5 hours to complete the journey .Find the distance , Vishal travelled by bus

Answer 1

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.

Answer 2

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.
