Question: 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? Think carefully first, then make a decision:
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. So the answer is 480.
