Answer:
480 minutes, and 6 hours
Step-by-step explanation:
At first we should know that
1 hour = 60 minutes
We will check which option is not equivalent.
1) 3 hours, 10 minutes and 190 minutes
3 hours, 10 minutes = 3 * 60 + 10 = 180 + 10 = 190 minutes
So, the pair of measurements is equivalent.
2) 240 minutes, and 4 hours
4 hours = 4 * 60 = 240 minutes
So, the pair of measurements is equivalent.
3) 350 minutes, and 5 hours, 50 minutes
5 hours, 50 minutes = 5 * 60 + 50 = 300 + 50 = 350 minutes
So, the pair of measurements is equivalent.
4) 480 minutes, and 6 hours
6 hours = 6 * 60 = 360 minutes
So, the pair of measurements is not equivalent.
