1.	(6) Out of 1900 km, Vishal travelled some distance by bus and some by aeroplane.Bus travels with average speed 60 km/hr and the average speed of aeroplane is700 km/hr. It takes 5 hours to complete the journey. Find the distance, Vishaltravelled by bus.by elimination method
Answer» ANSWER: Correct option is A 150 We know that, Speed= Time Distance ⇒Time= Speed Distance Let Distance Travelled by Bus be x so that Distance Travelled by AEROPLANE 1900−x Now, TOTAL time is 5 Hours 5= 60 x + 700 1900−x ⇒5= 2100 35x+3(1900−x) ⇒10500=32x+5700⇒4800=32x⇒x=150 KM

ANSWER:

Correct option is

150

We know that, Speed=

Time

Distance

⇒Time=

Speed

Distance

Let Distance Travelled by Bus be x

so that Distance Travelled by AEROPLANE 1900−x

Now, TOTAL time is 5 Hours

700

1900−x

⇒5=

2100

35x+3(1900−x)

⇒10500=32x+5700⇒4800=32x⇒x=150 KM
