Question

Out of 1000 km Sanjay travelled some distance by a bus and the remaining by a train. The bus travelled at an average speed of 70 km and the train at an average speed of 120 km/hr. It took 10 hours to complete the journey. Find the distance Sanjay travelled by the train.​

Answer 1

Answer:

bus = 70 × 2 = 140

train = 120×8 = 860

total =. = 1000

train = 860 km

bus = 140km

Answer 2

Answer:

Distance traveled by bus=280

Distance Traveled by Train=720

Step-by-step explanation:

Let distance traveled by bus=X

Therefore, distance traveled by Train=1000-X

We know that,

T=D/S

Therefore, time taken by bus= X/70

and time taken by Train=. 1000-X/120

According to question,

X/70 + 1000-X/120=10

cross multiplying on LHS we get,

120X-70X+70000=84000

50X=84000-70000

50X=14000

X=14000/50

Therefore, X=280

Hence, distance traveled by bus=X=280KM

and distance traveled by train=1000-X=1000-280=720KM

Hope this satisfies you.
