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 is 700 km/hr. It takes 5 hours to complete the journey. Find the distance, Vishal travelled by bus.

Let the distance travelled by bus = x

Speed of bus = 60 km/hr
As, 

Time taken travelling by bus =

Let the distance traveled by plane = y

As, total distance traveled was 1900 km
x + y = 1900 

Distance traveled by plane = (1900–x)

Speed of plane = 700 km/hr

Time travelling by plane =


Given, 

Total time = 5 hours



⇒ 32x + 5700 = 10500
⇒ 32x = 4800
⇒ x = 150 km

and y = 1900 - x 
         = 1900 - 150 = 1750 km


Vishal travels 150km by bus and 1750 km by bus

Two types of boxes A, B are to be placed in a truck having capacity of 10 tons. When 150 boxes of type A and 100 boxes of type B are loaded in the truck, it weighes 10 tons. But when 260 boxes of type A are loaded in the truck, it can still accommodate 40 boxes of type B, so that it is fully loaded. Find the weight of each type of box.
