Question

1)
Out of the 900 km distance Vasantrao travelled some distance by bus at the speed
of 60 km/hr and the remaining distance by railway at the speed of 90 km/hr. Totally
he travelled for 13 hrs. Find the distance travelled by bus. (Use two variables)​

Answer 1

Answer:

Step-by-step explanation:

Let the distance traveled by bus is x and by train is y km

so x+y=900----------(1)

$Total \ time =\frac{x}{60} +\frac{y}{90} =13 \ hrs\\\\3x+2y=2340-----------(2)$

Multiplying (1) by 2 and subtracting from(2)

3x-2x+2y-2y=2340-1800

x=540 km

Thus distance traveled by bus=540 km
