5:42 is 42 minutes, which is 42/60 = 0.7 of an hour
5:54 is 54 minutes, which is 54/60 = 0.9 of an hour
etc...

is your vertical axis a bit off? Surely it should start at 0 and increment in minutes up to the maximum length of time it's taken to get home or there abouts?
0-90 roughly?

Better presented as a bar graph IMHO.

Ah but it says "in hours". It's almost a trick question, to make you think about the units. As the other poster notes, it's because time is base 60 not base 10, but the chart is using decimal.

So 42 minutes to get home is not 42 or 0.42, it's 42/60, hence the 0.7

Just from a quick look, shouldn't the point for Friday be below the point for Wednesday?

It’s not clear if the commute takes places in all the time between leaving work and arriving home.

No stopping for petrol on Thursday?
