1. 12.88 km/h
2. 35.88 km/h
3. 8.71 km/h
4. 6.88 km/h

Answer 1

Correct Answer - Option 2 : 35.88 km/h

Given:

Travel 400 km in 10 hours.

Travel 210 km in 7 hours.

Formula used:

Average speed = Total distance/Total time taken

Calculation:

Total distance = (400 + 210) km

⇒ 610 km

Total time = (10 + 7) hours

⇒ 17 hours

Average speed = 610/17 km/hr

⇒ 35.88 km/h

∴ The average speed is 35.88 km/hr
