Question

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 hrs to complete the journey find the distance vishal travelled by bus

Answer 1

Let the distance traveled by bus = x

Time taken traveling by bus = x/60
Distance traveled by plane = (1900-x)

Time taken traveling by plane = (1900-x)/700

Total time = x/60 + (1900-x)/700 = 5
x/60 – x/700 = 16/7

8/525x = 16/7
x = 150

Therefore, the distance traveled by bus = 150km
