Question

If a log-boat takes 6 minutes to cover 1 km, then it will cover in 8 hours.

• A. 40 km
• B. 80 km
• C. 85 km
• D. 50 km
• E. 40 km

Answer 1

The correct option is B 80 km

Given,
The log-boat takes 6 minutes to cover 1 km.
Let's multiply on both side, So
60 minutes to cover 10 km
60 minutes = 1 hr

8 hours = 1 hours × 8

So, in 8 hours, the log-boat will cover:

10 km × 8 = 80 km

Therefore, the log-boat will cover 80 km in 8 hours.
