Question

The ratio between the speeds of two trains is 5 : 7. Second train covers 280 km in 2 hours. Find the distance covered by first train in 5 hours.

1. 500 km
2. 600 km
3. 530 km
4. 710 km

Answer 1

Correct Answer - Option 1 : 500 km

Given:

Ratio of speed of the two trains = 5 : 7

Second train covers 280 km in 2 hours

Formula used:

Speed = Distance/Time

Calculation:

Speed of the second train = 280/2 = 140 km/h

Speed of the second train = (140/7) × 5 = 100 km/h

Distance covered by first train in 5 hours = 100 × 5 = 500 km

∴ The distance covered by first train in 5 hours is 500 km.
