Best answer
Correct Answer - Option 2 : 270 km

Given:

The bus starts running from Lucknow to Kanpur at the speed of 40 km/hr and at the same time, the car runs from Kanpur to Lucknow at the speed of 50 km/hr

Both of them meet after 3 hours.

Concepts used:

Relative speed when vehicles move in the opposite direction = Speed of bus + speed of the car

Distance = Relative speed × time

Calculation:

Relative speed when vehicles move in the opposite direction = Speed of bus + speed of the car

= 40 km/hr + 50 km/hr

= 90 km/hr

The bus and car met after 3 hours.

Distance = Relative speed × time

Distance between Lucknow and Kanpur = 90 × 3 = 270 km

∴ Distance between Lucknow and Kanpur is equal to 270 km.
