Question

Q45. A person travels 285 km in 6h. In the first part of the journey, he travels at 40 km/h by bus. In the second part, he travels at 55 km/h by train. The distance travelled by train is

• A. (a) 156 km
• B. (b) 165 km
• C. (c) 615 km
• D. (d) 561 km

Answer 1

The correct option is B

(b) 165 km

Let time taken while travelling by bus = x h

Time taken while travelling by Train = (6 - x) h

Distance covered by Bus = 40x

Distance covered by Trains = 55(6 -x)

Total Distance covered = 285

40x + (55) (6 -x) = 285

40x + 330 – 55x = 285

X = 3

Time taken while travelling by Train = 3h

Speed of Train = 5 km/h

Distance = s × T

= 55 × 3

= 165 km Ans.
