Question

out of 900km distance vasantrao travelled some distance by bus at the speed of 60km/hr and the remaining by railway at the speed of 90km/hr . totally he travelled for 13 hours. find the distance travelled by bus​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The distance travelled by bus is 54 km.

Total distance = 900km (Given)

Speed of the bus = 60 km/h (Given)

Speed of the train = 90km/h (Given)

Let the distance travelled by bus be = x km.

Thus, the distance travelled by rail be = (900−x)

Time taken by the bus = x/60

Time taken by train = 900 - x/90

Total time = x/60 +  900 - x/90

13 = x/60 +  900 - x/90

13 = 30x + 1800 + 20x/180

2340 = 1800 + 10x

- 10x = 1800 - 2340

- 10x = -540

x = 54

Thus, the distance travelled by bus is 54 km.
