Given:

Distance covered by first bus = 320 km

Time taken by first bus = 8 hours

Speed of second bus = 25% more than first bus

Distance to be covered by second bus = 200 km

Formula used:

Speed = Distance / Time

Calculations:

Speed of first bus = 320 km / 8 hours = 40 km/h

Speed of second bus = 40 km/h + 25% of 40 km/h = 40 km/h + 10 km/h = 50 km/h

Time taken by second bus to cover 200 km = Distance / Speed

Time = 200 km / 50 km/h = 4 hours

∴ The time taken by the second bus to cover 200 km is 4 hours.
