Which pair of measurements is not equivalent?

3 hours, 10 minutes and 190 minutes
240 minutes, and 4 hours
350 minutes, and 5 hours, 50 minutes
480 minutes, and 6 hours

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.
