To make 3 km, Ben walked for 2 hours. Continuing at the same speed, how much time in minutes would it take him to travel 12 km?
Step-by-step reasoning:
480
We have 12 km / 3 km = 4.

So, the distance covered in 12 km is 4 times greater than 3 km.

The time taken will also be 4 times greater.

So, 2 hours x 4 = 8 hours.

We convert the time to minutes: 8 hours * 60 minutes / hour = 480 minutes.

The answer: 480
