Question

out of 1900km, vishal travelled some distance by bus and some by aeroplane bus. travels with the average speed 60km/h and the average speed of the aeroplane is 700km/ h. it take 5 hours to complete journey .find the distance ,vishal travelled 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 =

$\frac{(1900-x)}{700}$

➡Total time =

$\frac{x}{60} + \frac{(1900-x)}{700} = 5$

$\frac{x}{60} - \frac{x}{700} = \frac{16}{7}$

$\frac{8}{525x} = \frac{16}{7}$

$x = 150$

➡Therefore, the distance traveled by bus = 150km
