Question

out of 1900 km Vishal Travels some distance by bus and some by aeroplane bus travels with average speed 60 km per hour and the average speed of aeroplane is 700 kilometre per hours it takes 5 hours to complete the journey find the distance Vishal travelled by bus

Answer 1

total distance- 1900km
av. speed of bus= 60 km/h
av. speed of aeroplane= 700 km/h

total time vishal travelled by bus= 2.5 hours
i.e 60×2.5=150 km

total time travelled in aeroplane=2.5 hrs
i.e.2.5×700=1750 km

total time= 2.5+2.5=5 hours
total distance=150+1750=1900 km

Hence, distance covered by bus= 150 km and time travelled by bus= 2.5 hours
