Question

If a log-boat covers 20 km in 4 hours, then it will cover in 8 hours.

• A. 80 km
• B. 30 km
• C. 60 km
• D. 40 km

Answer 1

The correct option is D 40 km

Given,
The log-boat takes 4 hours to cover 20 km.

8 hours = 4 hours × 2

So, in 8 hours, the log-boat will cover twice the distance that it covered in 4 hours.

20 km × 2 = 40 km

Therefore, the log-boat will cover 40 km in 8 hours.
