Me on this i’m so tired and i can’t sleep until my progress is at 80 and this is the end of my year it’s at 79%

The bottom one is the answer

Step-by-step explanation:

The one on the right wouldn't be correct because histograms are supposed to always be connected from the beginning of it.

The one on the left is ignoring the fact that 40-59 and 60-79 are two different periods of minutes.

So the only correct on would be the bottom one.

2 5/8 is the final answer! : )
